Trapezoidal Rule & Simpson's Rule Estimating Definite Integrals Calculus 1 AB READ DESCRIPTION

[@a8bit8of8everything]

I'm in AP Calc AB, and I went from failing my first test (a 58 *cringe*) to getting the 3rd highest grade on my midterm (a 98 after a 15 point curve). Thank you so much you are a lifesaver!!

[@profrobbob]

+a8bit8of8everything you're welcome, that is certainly something to be proud of! Thanks for choosing my channel to study with and for sharing your success story with us...that's why we work so hard to keep this channel growing:D

[@Maistora11]

This is great, the formula for Trapezoidal rule seemed like magic before and now makes perfect sense. Thank you!

[@profrobbob]

Thanks for studying and subbing...please keep spreading the word:D

[@JohnsonR0x]

Great video! Appreciate you always posting free videos for everyone to learn :)

[@profrobbob]

+Johnson Li Thanks for sharing your appreciation! ...and we appreciate all your support as well!

Subscriber from Ireland! Hopefully all of your vides will help me in the future because I'm studying GCSE (15-16 year olds) and none of this is on the course. Love your vids anyway!

New #math lesson Estimating Definite Integrals using Trapezoidal Rule and Simpson's Rule.

[@alondramojico6838]

33:55: I think the beginning of Simpson's Rule should say (b-a)/(3n). Thanks for your videos.

[@allenogoti2912]

I thought I was the only one who had noticed that error

[@profrobbob]

+Allen Ogoti Thanks for pointing out my copy error. You and Alondra are absolutely correct. My video notes were written correctly so the answer is 20, but the formula is incorrectly copied on the board. I will make an annotation correction and post a new lesson with a permanent correction so user of iPads and iPhones will see it with Flash:) Thanks for watching all the way to the end and your help!!!

[@allenogoti2912]

+ProfRobBob Thanks a lot prof.I am taking my calc 2 exam on Monday and I am really enjoying the tutorial.I am now confident that I will not be in the dark regarding Simpsons and trapezoidal rule.Hey thanks a lot prof.I have understood the topic perfectly.Its my last exam at the university and I hope to graduate when If I pass.Give me any last minute insights on passing calc two if you can.Your work is great Sir!!

[@profrobbob]

+Allen Ogoti You have all of my best wishes on your final exam. You are going to ace that exam and graduate like BAM!!! I teach high school AP Calculus and we spend a lot of time going over old AP exams and practice problems. So I would say take as many practice exams you can find. If none are available work through chapter review practice tests or redo the tests you took during the semester. Just keep practicing:D

[@fahimma5559]

I hope the deadline or time limit has been abolished and now you wouldn't need to be in a haste.Your videos with a longer time are much more enjoyable,understandable and knowledgeable:)(:

[@profrobbob]

M A Fahim THANK YOU...yes, in the beginning I had a 15 minute time limit but I also never dreamed that I would still be making videos almost 4 years later, when I made the first ones just to help one of my students:)

[@Adhithya2003]

Thank you sir. What reference book is good for this topic ?

[@paulreed9950]

on your table example I believe there is an error because it should be 2(3.317) instead of 2(3.17)

[@Qbabxtra]

Is this still high school maths for americans? Or are we over to the uni/college level now?

[@profrobbob]

Some students take this in high school thru AP courses...otherwise it is college level work.

"I introduce how to estimate a definite integral using the Trapezoidal Rule *buy* using our knowledge of basic Geometry" by, not buy

[@profrobbob]

You are so kind!!! Thank you for watching my lesson and for the help:) I corrected the video description. Here is my website where you kind find my lessons organized by chapter and topic, www.profrobbob.com

[@MR-kp5nh]

Sometimes I wish you would just work the problems for us instead of making me spend so long to see what's going on. So much talkinnnnggggg

[@profrobbob]

...that's why there are so many choices on youtube!

[@MR-kp5nh]

But I like yours and khan academy. I just sometimes wish you'd be a bit more concise. My apologies.

[@profrobbob]

no offense taken!

[@zktec1]

Wow! You're dead wrong and you're not going to take much away from mathematics unless you understand the underlying reason for the rules--not just following the rules. There are alot of other teachers on youtube, but i choose this guy over the others because he does provide those explanations.
