I Can't Believe They Did This

In this video I will show you different versions of a math book that I have that. The book is the legendary Calculus book written by George B. Thomas titled Calculus and Analytic Geometry. In the newer version there are solutions to only the odd problems, but in the older version you have almost all of the solutions. There are also significant changes in content and presentation. I hope you enjoy this video:)

I've a 5th edition of the book. It has answers to almost all of the problems. I think they start to offer only answers to odd(or even) problems in the 6th or 7th editions. If you self-study calculus, get a copy of the 5th or earlier edition to get all of the answers. The 5th edition was printed in two colors. It was a gem. Put a copy on your bookshelf for handy reference.

Awesome!!

[@glennedgar5057]

In the late 1960s I lived in a very rural and poor part of se Ohio. As a freshman in hs I figured out calculus on my own with this book. The answers were instrumental. Over the length of high school I figured out 2 years of college math and started out as as junior in college. I had no help in studying the subject. Now that I am close to 70 years old I found out a very valuable lesson. To study math or the sciences professionally, one has to be invited in. I was not invited in and had a successful career in engineering.

[@raul0ca]

I had a chance to teach Chemistry Lab to majors and non-majors. Pre-med students were the worst since they didn't care because they knew they would never use it again. Engineering students were the best because it was another world even though they would never use it again.

Glenn, Excellent post; although your 'invited in' phrase caught me a bit perplexed, so please elaborate. Thanks.

[@SeattlePioneer]

You had a lot more IQ points than did I. I was a mediocre science and math students in HS, and just managed to fumble my way through trig. Circa 1990, I decided I could do better than that, so at age 40 I went back and took math classes through two quarters of regular calculus, and got 4.0 grades. The third quarter of calc I dropped out, then went back and took it again, and again couldn't complete it. That was the end of my math studies, I figured I had done all my intelligence would allow me to do. Circa 2019, I took a computer machining class. The TA for the class was a third year engineering student. When I related the anecdote above on my math studies, he told me he had taken third quarter calc THREE times before completing it properly! I was impressed ---I didn't have enough courage to do that, and figured I was just limited out on IQ points. I recall a third quarter calc teacher lecturing the class --- saying that he expected a SOLID HOUR of study for every class day to keep up. I was spending THREE hours a day to keep up! Pretty much every math class had someone complaining "WHY do we have to study this?" That was until calc ---and after that no one asked that question any more. As a marginal math student, I can compare math study in the mid 1960s with that in the early 1990s. Computers and graphing calculators were a great aid for me in being able to visualize equations by graphing them on a computer or calculator. I figure that computers have made it possible for marginal math students to learn more math because of that.

[@JohnBrown-wk4io]

@@SeattlePioneer I think one of the biggest shifts in being able to learn decades ago versus now is the internet. Back when, what you had was what you had & if your teacher was mediocre at teaching something & the books were less than helpful then that was it. Today on almost any subject some one some where has uploaded material & in some cases will actively respond to inquiries on problems so an eager learner has resources at their disposal undreamt 40 years ago.

The great innovation on the obsolescence front is that new textbooks come with a subscription to a related website for one year only. You think you need that to keep up with the rest of the class.

[@ZipplyZane]

In high school, they always had two versions of each book. The Teacher's version would have all the answers, even often working them out. But the student versions were always like this, with only odd answers. I believe the idea was that the teacher could assign even problems without us being able to get the answers, but we could still get help on the similar odd problems.

Yes, that’s right. I remember my teacher have the teacher version with all the answers. The students were assigned homework from the even-numbered problems.

[@myst0dreamer]

I was just browsing around KZbin and I saw your video. I'm pretty sure I used this book in the early 80's, it was purple and thicker. But what caught my attention was the older book here, because it looked to be the same vintage and maybe title as the book my father used in college in the early 50's. We had the book for a long time, but unfortunately I don't have it anymore. I think in those days they didn't learn so much math in high school, so that might explain why that book had the unusual content it had. He was an engineering major, and other math books he had included a book on Trigonometry. The older books looked like they were harder to read, they didn't bother much with pretty sections, illustrations, etc. I still have my father's 18" wooden slide rule that came in a leather case, some old drafting instruments, and tables of logarithms and the like which were much more detailed than the ones I could find myself when I needed them. 20 years or so ago I took the whole series of Calculus courses again (sorta for fun), and the main thing that changed is that I had to learn how to use a graphing calculator.

[@hcf51213]

I had a wonderful and unexpected run in with this book (3rd Edition) today! I was driving upstate to go hiking and drove past a house with 4 old wooden sheds and a homemade sign that said "All books .50 - $1, self serve always open". The sheds were filled with shelves of all kinds of books you can imagine, and as luck would have it, there was even a small math section! There were a few interesting finds, like "Arithmetic for the Modern Age" by Aaron Bakst, but this book by Thomas caught my eye immediately. I love self studying from the older books, and I'm stoked to have this one in my collection now. I usually browse ebay and abebooks, but today, the math gods brought me to a few sheds way out in the middle of nowhere to get 900 pages of math for one dollar :)

[@harrybarrow6222]

When I was in (high) school - 60+ years ago - I remember text books like this. The student version had answers to odd numbered questions, but the teacher version had answers to them all.

[@machintelligence]

Not all of the answers were correct though. I remember some frustrations that were only resolved by asking the professor to work the problem and having him admit that the answers in the back of the book was wrong.

[@richardhole8429]

As a teacher I appreciated having answers for only half the problems. I would assign homework with some without answers to see the students mastery and others with answers to build their confidence. Publishers provided an answer guide with all included but available to teachers only .

[@johnfitzgerald8879]

That was what I always thought was the reason books had only the odd numbered problems answered.

[@rickhole]

Most texts have ample number of problems so someone self-studying still has plenty to checkable exercises. I think if I were still teaching I would give two assignments, one with a mix of answered and another all unanswered and give bonus points for those. At least try that for one semester. I would post on my office door solutions to the unanswered problems after the assignment was closed, or cover them in the next class.

[@edwardarruda7215]

My first Calc professor said some of the exam problems will be from the end of chapter problems. The ones without answers in the back.

[@dmitripogosian5084]

Yes, that is the reason, except my students always demand to see answers to the other half as well. I am tired answering emails 'I solved problem 3.22' (even) - where can I find the answer ? Given that most answers for classical texts can be found online now, even/odd split is not greatly useful. I would more appreciate a separate bank of problems, which are not in the textbook

[@rickhole]

@@dmitripogosian5084 I assume you have the teacher's answer booklet with all the answers. If you prefer your students to have access to the answers you could provide them in class before or after the assignment is complete. I would post them on my office door after they had turned in their homework.

tg, ch, sh are all continental European notations. I grew up in Montreal but went to a French high school from France and this was the notation. French speaking Quebecois are Americanized and thus use sinh, tan etc... Text book in French in Quebec are often translations of American books because of the mismatch especially pre-1980 between mathematics in French Lycées and Quebec high schools. (Far more abstract math in France: delta, epsilon, number theory, abstract vector spaces, etc... all over the place in French high schools.). Also in France, [a,b] means a closed interval. If it is open on the left, it is ]a,b]. ]a,b[ for example is less confusing than (a,b). Finally in French, German and Japanese, a field (R, C, etc...) is called a "body" (corps,Körper and 可換体 ) so it is less confusing. Chinese use 域 which is more like region but their vector field is 場 as in Japanese. (field!) (I live in Japan)

While I used the 1965 Thomas work for three semesters between 1967-68 (up to calculus of several variables), I did find the treatment of LIMITS to be severely wanting, in that I was never quite able to grasp the concept of limits and continuity. The Pearson edition, OTOH, begins with a review of basic function topics (algebra, composition, and transformations of functions), and does a rather superb job with limits and continuity.

[@tomgeorge7281]

I used various editions of Thomas in high school and college (the 1970s and 80s). We had the answers to the odd problems in the back. In college we could buy the solutions manual, which showed how to work the problems.

This is common practice in many textbooks. Its basically a way of helping teachers by giving them half the questions that they can use for homework assignments or tests. Basically, it helps teachers from having to come up with their own questions. This is definitely not helpful to those who are self-taught, but the reality is the majority of learning is through tutalage or institutions. Its understandable that publishers cater to their primary audience, educational institutions.

[@garysimpson7326]

I used Thomas as an engineering undergrad at TAMU many years ago. It was the Alternate Edition.

[@RN1441]

When going through engineering undergrad having answers available to the diagnostic problems was essential to confirming that one was really understanding the approach to the material. Doing an exercise 20 or 30 times incorrectly is not only wasting your time, but it's reinforcing an incorrect approach. Having the answers was a minimum though - having an example of at least a similar problem was extremely useful. In one course in particular (field theory) we had a solutions manual that was notorious for being wrong about half the time but that was OK because it was actually excellent with problem setup and descriptions, so spotting where the author had made a mistake was a useful exercise in itself.

I taught the first 2 parts and they needed a recommendation. They used a poor text by Protter and Morrey and wanted a change.

IMPORTANT: DIFFERENTIAL EQUATIONS are where the information of this book is used in math and science. Solving those is necessary to USE most of the calculus results.

[@sushibar777]

I learned Calculus using this 3rd Edition. It was an excellent textbook. We went through the entire book, front to back, everything, including complex numbers, which was then definitely part of a standard calculus course. Since Calculus and complex numbers are essential to Physics, and since many Calculus students are also studying Physics or Engineering, it's hard to think that any serious Calculus textbook wouldn't cover them. The omission of any of the original list of topics is a bit perplexing. Most people using the book do so as students in a class, and not for self-study, so hitting a section that a student doesn't fully grok won't lead to them stopping using the textbook, as the class will be moving on to the next topic regardless. The professor, TA, or other students can help with understanding of any sections where the student has difficulty. Having answers only to odd (or even) problems is not that unusual. It gives instructors that ability to assign problems in exams. There will be a professor's answer key that will have answers to all questions. As you point out, there are more exercises in the newer book, so it seems like they haven't reduced the total number of answers.

I first encountered Thomas' book ( 3rd edition) in the spring of 1967, fresh from three years in the army. That first semester was the most difficult thing I've ever done in my life. I checked. It has answers for all of the questions. I also checked "Advanced Engineering Mathematics", bu Kreyszig, 2nd ed. It only has answers to every other question. Same with "Modern Mathematical Analysis" by Protter and Morrey. I managed to get through all three so maybe losing the answers to even numbered problems isn't the end of the world

[@EddieVBlueIsland]

I got the fourth addition - very good for self study (along with Advanced Algebra and Calculus Made simple by Gondin & Sohmer). Funny error on page 489 in calculating the Syncom satellite (Geo-sync) orbit (Worked Problem #3 using logarithms) does all calualtions correct until the very end answer getting 22,500 miles instead of 22,300 miles and invites the readers to find the error - I found it years later when I got use to spotting (km to mile) conversion errors.

[@markharder3676]

Medical students often encounter texts that are updates of very old editions. Eventually, the updates include the original author's name in the title, as in this case. I found it quite odd for a math book. But then again, why not? I referred to my brother's copy of the '60s version of Thomas in grad school when I needed information beyond the level of my own college textbook (Johnson & Kiokmeister). I think the Thomas was better. With its help, I could solve a homework problem requiring multiple integrals in an hour or two. No lectures or hours of study required. Very clear writing, it must have been.

I didn´t know you spoke such good spanish! Me estoy volviendo loco para encontrar esa edición en español, aunque me conformaria con una en Inglés. Thanks for your motivation

[@TheDesertRat31]

So is an older copy of Thomas' book a good one for self study? I was always " scared" of calculus, probably due to the horror stories from friends. Math was never my strong subject in school, but I've recently been wanting to tackle calculus. A more mature mindset has allowed me to go back and get a lot better at math I was terrible at as a kid. So, just wondering how this book rates as a guide for self study. Thx.

[@deadman746]

That was my calculus text in high school in the 1970s. Nice to see it again.

Calculus "clicked" for me as a senior in high school, and yes it was Thomas' text we learned from.

[@richardrigling4906]

My version is the big Orange version, 4th edition, 1968, with answers to all the problems. It was brand new version when I took Calc I & II in '68 - '69

[@cunningba]

I too have a 3rd edition, from my freshman 18.02 course in the Fall of 1966 at M.I.T. About half the entering class had had AP Math, so we started with the 2 semester calculus course (which corresponds to the 3rd semester course most places). Thomas was one of two textbooks we used for the course. The main one was a set of notes by Arthur Mattuck titled Vector Integral Calculus. Green's Theorem, Stokes' Theorem, div, grad, curl, all that good stuff. Your copy of Thomas has different binding than mine. Mine is wine colored with black background under the title one the spine. Is yours a library binding or just a different printing with a different binding? I notice that I no longer have the green dust jacket that came with it and followed it around for years. Don't remember when I ditched the DJ, but it must have gotten a little too shredded to be worth saving. Easy to do given how thick the book is, that I've had it for over 50 years, and it has followed me around on I don't know how many moves. Survived many cullings too. When thinning my library and I figure I just need one calculus book, I unhaul all the instructor copies from when I taught calculus and keep Thomas.

[@jirimondo]

Thomas was still teaching 18.01 and 18.02 in '74-75 (my freshman year) as I recall.

[@cunningba]

@@jirimondo Mattuck and Benny were teaching 18.01 & 18.02 my first semester. (Remarkably, Quillen was my recitation instructor for 18.02.) I met Thomas briefly a few times at various events in the math department during my years there.

[@Cyclonus-fc1xx]

Can you review the 4th edition of Real Analysis by Royden and Fitzpatrick? It covers some measure theory unlike the other Fitzpatrick book was wondering if you thought it did a good job and if it's worth picking up

P.S. We used slide rules back then as calculators. I still have the original text, and refer to it periodically.

[@johnishikawa2200]

Looking for a snazzy, inspirational text to add to my arsenal of math books. Eventually I'm gonna dive back into calculus, and that book looks just like what I need. I have a great text by Anton, but I've already done all of the problems in it years ago. The older texts are underrated in my view. I love my differential equations book by Boyce and DiPrima, and I also have a well worn calculus book by Lloyd L. Smail, published in 1953. If I have to order the book by George B. Thomas in this vid., would you please tell me what the ISBN no. is? I've written down math texts from other videos of yours, but this one has really piqued my interest!

[@M5guitar1]

I went to Stanford in 1979 and used the 5th edition for my engineering major.

[@superiontheknight963]

So I noticed that there seems to be quite a lot of problems to work through at the end of each chapter in the third edition of the book(Which is excellent!). There seems to be review questions, as well as some miscellaneous questions to work through. I suppose my question is, what is the best way to tackle these? I have two different ideas I could use, each having their own pros and cons... Method 1: Do only the review problems, and skip the misc problems. The idea behind this is that I can come back to these misc problems once I have finished the book, and refresh my memory on things that might have been done a little while ago. I've seen something known as the so called "forgetting curve", that suggests returning to the subject multiple times can make that curve less steep as time goes on. So I've thought to myself: "Perhaps I should leave these problems here, as an incentive to come back later". I don't actually know how much truth there is to the forgetting curve, but it is enough to make me question. I also don't fully understand proofs at of the time of writing, and yet there are proofs in some of these problems for me to work through. So part of me thinks it might be a good idea to come back to these problems once I've read through my Discrete Math book some more and get a better understanding on what proofs even are. To give you an idea on how much progress I've made with my Discrete Math book, I've only read the first three pages so far(So not a lot)... A BIG con with all of this though, could be that I get into a bad habit of skipping loads of problems, and I really don't want that to happen. Method 2: I could go ahead and do it all in one go. This could work better, as I would likely get an even deeper understanding than what I already have much more quickly. The struggle with working through proofs, even though I don't know how they work too great, could also be beneficial as I would likely get at least something from it. The cons that concern me have to do with getting stuck on a problem, and time. I could be spending some of this time getting an idea on what some of the other stuff is like(provided I understand the material up to a certain degree). In addition, this persistence on trying to work through every problem as I come across them could make it even more difficult for me to be willing to let go when necessary and move on. Yet I still would like a deep understanding at some point nonetheless... So what do you think? Am I overthinking all of this? Which method is the way to go? Or maybe there's even a third method that I haven't even thought of? Looking forward to any responses I get! Thanks!!! :)

[@stephenbeck7222]

If you’re just working through it to learn on your own, I say work the problems you want to work. These textbooks normally have more problems than ever needed so teachers have enough to assign as they want and perhaps give multiple versions of assignments. I wouldn’t leave problems to come back to later, because if you do them the first time and then work through the rest of the book, you probably forgot all the specific solutions to those earlier problems - it may even be helpful to work some of the problems twice and compare how your solution methods changed over time as you got more experience and also learned more advanced topics.

[@Allen2]

My Thomas from 1972 is the "Alternate Edition " which the publisher's note describes as after the Third Edition, with the section on limits "not as developed as in the Fourth Edition."

[@timmy---]

I used the 3rd Edition, 3rd Printing in 1962 as a freshman at MIT. We covered the entire book, except DE in two semesters, 18.01 and 18.02. I had George Thomas as a lecturer for 18.01. We also had most of the problems assigned as homework and a classwide exam (entire freshman class) every third week. The same was true for Physics and Chemistry, who had has class-wide exams alternating every third week. I can't say it was better or worse than any other book, as I struggled with every subject, but at least I passed.

[@thomasw.eggers4303]

I also used the 3rd Edition as an MIT freshman but in 1960. I still refer to it occasionally. Non-relevant Thomas story: Prof Thomas was late for class one morning. An almost-late freshman showed up, saw that the Prof had not yet arrived, and starting writing the digits of PI on the (black) board. He got about 50 or 60 digits written, when several freshmen simultaneously shouted out a correction. The digit was corrected, and the freshman continued writing more digits. He got maybe 80 or 90 written before Thomas showed up. Thomas looked at the string of digits, said nothing, but gave his lecture, carefully writing above and below the digit string. At the end of the lecture, the digit string was still there.

[@johngreen3543]

I took Calculus in 1965 and we used the Thomas Text.The large version was divided into 2 books. The First one was for Cal 1 and 2 and the 2d book for Cal 3. They did this I think for academic reasons and to spare the student on codsts. So do they have 2 parts to the current one? I got an A for Cal 1 and 2 and a B for Cal 3

Now it is 14th Edition. I am also also crazy about textbooks, especially old textbooks written by dead authors. Nowadays I have been buying from Abebooks a lot, and I think some modern textbooks nowadays are like magazines, colorful but diluted, whereby the drawings does not serve to illustrate but to distract. and confuse. Remarkably, books from India and China are still preserving the traditions.

I feel the same way about the Larson pre-calculus text (2e). The later editions took out explanations which I thought were best to leave in. The section on finding asymptotes truly suffered in later versions. Have you done a review of these books by chance?

[@TheMathSorcerer]

Not the earlier editions I should check those out, thank you!

[@billmorrigan386]

You might want to use the books with a title _Elementary Algebra and Trigonometry_ by either Larson, or Stewart, or Swokowsky. Those are more comprehensive textbooks. Precalculus versions are truncated, even dumbed down a little bit. Personally, I would not buy a book with a Precalculus title when _Elementary Algebra and Trigonometry_ titles are available that go deeper and cover more ground. That's because a precalculus book looks somewhat similar to an HS book which are a bit primitive to be completely honest.

You just gave another good and funny example about how the olfactory system can contribute to motivate and mobilise one’s attention to study science. I can attest to that: the old books I like the most usually also have a pleasant smell, whatever that means. And frankly I don’t really want to know what it is that had to rot away over many years of shelf life to create this “old smell of wisdom”. Could be skin and sweat from other readers, could be insects and their droppings, could be certain moths that like to chew on paper - but didn’t succeed because there was just too much good math on the pages 😂.

[@DavidRLentz]

I am abysmally poor at maths. This centres especially upon working basic operations (addition, multiplication, etc.). I simply stare blankly at cyphers and symbols that my mind finds meaningless, especially in the aggregate. By contrast, I am a brilliant speller, good with the technicals (usage, grammar punctuation, etc.), and an excellent writer. I am an aspiring novelist--popular fiction; I have no pretensions to literature. Still, some things arithmetic and mathematical intrigue me. Alfred North Whitehead explained in an essay I read in an English composition course that these fields are about quantification. Well, that was encouraging. I quite enjoy quantifying and measuring things. Which brings me to my main points: 1) the circle and the square (two-dimensional geometry): and 2) the sphere and the cube (three- dimensional geometry. I am a fair pencil artist and pen & ink illustrator, who has made a considerable amount of graphics, signage, logo design, and similar. These have shown me (artistically, rather than geometrically) that the square has greater area than the circle, and the cube greater volume than the sphere. But at what rate of difference? Would this be a ratio? A percentage? Can one learn anything else of significance from the basics of the constructs? Yes, I understand that the sphere and the cube are two of the shapes of the physical world, along with the cylinder, the cone, and the torus. I do not consider the other three; I am not about to bite off more than I can chew!
