Mathematical Proof Writing

The cool thing about this man is that you can easily watch and enjoy his videos even if you’re really bad at math (like me); obviously if you are at a certain level you can enjoy his videos even more, but this channel is still the best math channel I’ve ever laid my eyes upon

[@rodneycummings1456]

I had a professor named James Lang at Valencia College who taught me how to write proofs in his Logic and Proof class. I still to this day structure my proofs the way he taught me. The book that we used in his class was Mathematical Reasoning - Writing and Proof.

[@corbinwilson660]

Nothing like coming inside after a long day of work in 100+ degree weather and be meeted with a math sorcerer video. Great stuff man. I’m currently working through Jay Cummings book, going through a subsection a day and it has been helping me a lot. Really like the structure of his book too, makes things easy to follow and you get introduced to proofs immediately instead of having to learn sets and logic first. I’m actually on the sets section right now, and it is great.

Thanks Math Sorcerer. I took a proofs class twice, flunking, then getting a B--. I'm continuing to study proofs on my own, and I'm much higher on the hurdle than before, so I just need to continue, and I can see mathematics opening up for me slowly but surely. It really is great!!!

Off topic of math proofs I guess but: I got a Calculus book in the mail yesterday that is so easy. Its Calculus by Marvin L Bittinger. Its kind of like the Blitzer math books in the way it has easy to understand explanations and detailed explanations. I love that it has exercises in the margins next to the explanations. After an explanation, it will say go do exercise whatever and the exercises are right there in the margins next to the explanations. The back of the back has all the answers to the exercises in the margins and answers to the odd numbers of exercises at the end of each section. So there is a lot of exercises in it to do and you can check most of the solutions in the back. I think its probably either a textbook for a course in college level Calculus 1 or a high school course in calculus. Its not as challenging as the Stewart book. But its probably good for a beginner. Mine is the fourth edition. It was a book in college library because it has a old library cold holder in the back. National University Library San Deigo is tamped on the side and inside. So happy with this Caculus book. Its perfect for me.

[@jennifertate4397]

Hammack is really good for self study because the answers are detailed, and sometimes exploratory, and every other problem is answered. I usually use the answers as "hints" by slowly revealing a part of the answer, then trying on my own to move forward, then looking at the next part of the answer if I get stuck, to see if I'm on the right track or to learn the next move. And sometimes I get on the right track, and can then finish the rest of the proof on my own without having looked at the entire answer until afterwards! That's why I think providing answers is important because those who really want to learn, won't overly depend on answers.

I think a lot of people initially dislike proof writing because they had a bad experience in geometry in high school. Many of my friends hated geometry, and the teacher was awful. I wound up teaching myself, but i didn't just learn enough to pass a test. I enjoyed, "English for Math Students." So, I read more about proofs. This proved to be very helpful in college. Learn to write. Learn to write proofs. You'll math a lot better! (Yes, that was "math" used as a verb. 😊 )

Thank you so much for the book recommendations! I will complete Calculus III in December and as a transfer student to the University, my first required class is Intro to Proofs! I'm definitely going to purchase these books, because when you said you can be a rock star in Calculus, but the Proof level will make you want to give up (paraphrasing), that made me want to start studying now! My end goal is receiving my Doctorate in Mathematics Education, and I WILL do it; however, it's going to take a lot of hard work, dedication and studying, and I am up for the challenge.

[@XenOz3r0xT_88]

Thank you for this. This gave me back the confidence to re-learn again. I have my degree in Physics and am currently enrolled in grad school for my masters in math. I figured let me do a masters in math because the research I was doing as an undergrad in Physics was under the dept head of math at my school (my research is in fluid mechanics). The first class I took last semester was real analysis and we used Rudin's book as you mentioned and omg did I feel so out of place seeing none of my Physics knowledge or skills (even my math skills) could help and barely passed by the skin of my teeth. Now I am taking probability and its been 3 classes so far and was thinking my knowledge in statistical physics will help but it looks like its a no go again. Luckily there are resources like your videos and others and many books to help bring me up to speed and I feel more confident to tackle all of this again after feeling I am not good enough.

I'm currently a first year graduate student in mathematics. Really struggling with extremely short course timing and professors who rush things. I am usually very slow when I do things myself, so often times I have to look up solutions after I spend like hours on one problem. I've hated not being able to do many problems myself over time, but even few of those moments where I actually took a day or even more so to completely understand what actually went on with the problem, the logical structures, and the corresponding implications - and then wrote a very detailed proof with every step highlighted - those are moments of accomplishment to me, as I did exactly what I aspired as a child to do - to learn about something intricately. Hence, the short timings and really oppressive deadlines has been a constant source of discouragement and self-deprecation. Thank you for your videos, as I feel inspired to keep moving forward. Good day, sir.

[@dhickey5919]

Thank you for this video. One of the best early reasons to learn math is to separate opinion from logic and deduction. We all could learn to spend more time thinking over the merits of our arguments (math or otherwise) before expressing ideas out loud.

I really feel that these types of 'talks' should be a necessary part of the first few classes in first year university, and maybe for ANY course that's taken at the college level. Although it's wasn't always the case, my experience was that, you'll spend most of the year trying to become adept at a particular subject, and then only near the end of the course, when you have all of the skills to do a problem (I'm talking about problems that are not directly spoken about in the course), do you get the reveal, a demonstration of how those tools are used. Prior to that moment, you might not have even grasped exactly what the tools are for and why they'll be useful. Intuitively, it feels as if that part of the process, at least the explanation of it, could come earlier on. I don't know, it's just an intuitive feeling I have. A simple class named 'why you need this skill' might give a little bit of extra motivation. One of the classes I really did enjoy was Graph Theory because, early on we were given tasks that showed exactly what the tools are good for. I was like, "WOW... you can do that with this?...". I even found the answer to a line puzzle that I had struggled with as a child, and gave up, thinking it was impossible; turns out it WAS impossible, but I learned to prove it, from the theorems we were taught in that class. There were quite a few 'WOW' moments throughout that course.

[@franciscodanieldiazgonzale2096]

In a University setting there should be room for the student own thinking and for him/her to be challenged. I know about the pressure with the grades. But this is not about the grades, it is about to learn how to think and how to be an independent thinker. To accomplish this, the student needs to feel the struggle and to learn how to overcome it. Part of this process is to think why you need to do the things you are doing. You need to reach some idea on your own, even a wrong one, that works temporary for you. Only then, you will appreciate the insight. In my case, after many issues, I learnt the hard way to appreciate this setting in University. It is what makes those places what they are, in fact.

It's like programming once getting the vibe it becomes sort of a language and no needs to think about what algorithm you used or anything.. the argument makes sense I kind of had to think everything tell I took another class in proving logical statements with logical trees

Writing proofs is hard at first. I saw the first proofs in middle school (just before going to Uni) and that was just fine. But then in the first year at EPFL, in the LinAlg course, we had to come up with our own proofs of stuff. For the first few weeks it was just blank minds and blank stares, but then it was as if a switch had been flicked. Hence, in my view, at a beginner's level, the best way of learning how to prove stuff is trying to prove stuff. Once you've got that you can start working on improving the style and so on.

The Goldbach conjecture is true, every even number x is always the sum of 2 prime numbers because with every increase in value of x (always 2 integers more than the last) then all odd numbers below x/2 move one further away from x/2 and all above x/2 move one closer, so the odd numbers always pair with another odd number. So if one odd number a distance k below x/2 is a multiple of a Prime (Pn) then we can rule out it and the number a distance k above x/2 as being a prime pair. So by eliminating all multiples of P

How do people who serve as advisees for a math REU even go about finding topics that would be appropriate for a reasonable motivated undergrad to tackle, and how does that process differ from finding such projects for a master's student , or people in the initial years of their PHD.

Hey love your channel and may I ask a question: If in set theory, I can create a relation which takes a set of elements which are propositions (like set a is a subset of set b) and map it to a set of elements containing “true” and “false”, then why is it said that set theory itself can’t make truth valuations? I ask this because somebody told me recently that “set theory cannot make truth valuations” Is this because I cannot do what I say above? Or because truth valuations happen via deductive systems and deductive system is technically not part of say, the first order set theory ?
