[@vinteachesmath]

I appreciate the legend status label but I have a long ways to go! Best wishes on your AP test!

[@Abbas-zy6us]

Hi thanks again for all the help, however i couldnt bother but notice that on question 91 isnt the function f(x) also increasing because all values of f"(x) are positive?

[@Mandq.]

man you are the best istg

[@vinteachesmath]

I appreciate the vote of confidence! Which topic(s) are most challenging in AP Calculus? Also, I have a few live streams scheduled in the week leading up to the AP Calc exam!

[@Mandq.]

@@vinteachesmath tbh I see AP Calc AB kinda mid to easy, just optimization problems are killing me 🫠

[@gregbaboudjian550]

I understood all of this hopefully I do good on the calculator mcq for my final

[@vinteachesmath]

I hope your final goes well! What topic(s) do you think are most challenging in AP Calc?

[@kromydas5063]

​@@vinteachesmath people at my school say solids of revolution, but I don't think any topic is TOO challenging. It is the silly mistakes / brainfarts that screw my tests up, making em go from an easy 95+ to 86s. On good days though I can easily get 97 ish which is whats bring my grade up.

[@ryanbacher5434]

Thanks for the help👍

[@vinteachesmath]

Happy to help! Hope your AP test goes well!

[@ishtiakyousuf5655]

Hey! loved your vid my calc ab exam is on monday, would you ever do this again with a more up-to-date mcq test and maybe some frq's aswell? Thanks a bunch!

[@vinteachesmath]

I made practice test videos for each of the 10 units (with original MCQs and FRQs); otherwise, I am waiting for collegeboard to release another practice exam to the public. The questions from the old exam are still good for today!

[@Erorro243]

Thank you :))

[@vinteachesmath]

You're welcome! I am doing 4 live streams in the days leading up to the AP Exam!

[@ThuyNguyen-lf2sm]

Do you go thru the whole AP cal AB exam? Which review book is this, Princeton or Baron? Thanks!

[@vinteachesmath]

This is an actual AP exam released by college board. But either of those books are great for practice. My AP Calc Review Playlist has a mix of multiple choice and FRQ practice.

[@dinislamloks2616]

Where I can buy allowed calculator for exam?

[@vinteachesmath]

Amazon will have any calculator you need. You can get a TI 84 plus: amzn.to/3v9mJzv There is also the standard TI 84: amzn.to/3v9mJzv Otherwise, you can go to staples or best buy.

[@davidp2537]

For number 80 during 6:24 , the instantaneous slope of f'(2) looks like to be 0, so shouldn't it be an inflection point?

[@am1r883]

we have the graph of f` and want to see where f has a poi so it'll have a POI when f` changes from incr to decr or vice versa but it stays increasing so it's wrong

[@klukyapb5361]

no that is the point that the graph has a relative maximum

[@ervanaz4850]

Hi, i want to ask a question about calculators. I got a nspire cx ii cas calculator, but i often see that people use ti-84. I dont know about the differences of calculators and which one is better. Can anybody share their experiences of these calculators. I am little confused. If needed i will consider switching to ti-84. I am a BC student btw.

[@ervanaz4850]

Thanks for the video by the way, your explanations are very clear

[@vinteachesmath]

I believe once you know how to use the nspire cx ii, you will be like Thanos with the infinity stones. That calculator is super powerful; most schools do not have the budget to order class sets of the nspires so they go with the TI 84 Plus CE.
