Nice. It’s not guaranteed to be on the exam, but in my experience there’s usually either 1 mcq or one part of an frq. And every point counts! Good luck!

Welcome! Good luck!

Not for me lol

@@trnstdev2958sameee atp i just want a 3 at least 😭

hell yeah

​@@trnstdev2958we're in the same boat

been getting comfortable 5s on practice, hopefully exam tmrw isn't absurdly hard for no reason

Definitely wishing everyone a 5 on this thing!

love to hear it! happy the exam went well for you!

best of luck!

I agree!!!!

good luck! hope you get that 5!

Definitely a good one to know shows up on FRQs from time to time. Good luck!

@@turksvids for the cross section of a rectangle, is it not integral [a,b] (k*s) dx? as opposed to k*s*s, wherein we'd multiply base twice which doesn't follow the area formula for rectangle b*h?

Nothing super concise, but a lot of videos: www.youtube.com/@turksvids/search?query=related%20rates

you're in good company! good luck on the exam!

Unit 10 is 17-18% of the exam, according to College Board, so it's a lot for sure. Series FRQs: kzfaq.info/sun/PL6iwkLfBjZiwheTEUA-N7ujqhLZiTVwvZ Series MCQs: kzfaq.info/sun/PL6iwkLfBjZiyqUTZEzhT1fkU4XDwnfuRJ Good luck! Please share with your friends/classmates!

For frqs u don’t know and u wanna give up try to go for setup points

50/50 shot. They actually do put polar on it every year, pretty much, they just (annoyingly) only release one set of FRQs per year. (Which does save me hours of work since I don’t have to make videos for them!)

The only thing I'd add is you should say something like r'(0) < -6 and r'(3)>-6 (or vice versa) before making the conclusion, otherwise looking good--assuming you meant r'(m).

Average rate of change will basically always use those exact words. Average value will almost always just say “find the average __________” where the blank is the output of some function in the problem. So it might be temp, weight, amount of rain, height, etc. hope this helps!

(this assumes there are two curves bounding the region...) The diameter is in the plane, so the diameter would be s = (f(x)-g(x)) or (top - bottom). That makes the radius s/2. The area of a circle is pi*r^2, so pi*(s/2)^2 = pi*s^2/4. But then you only want half of the circle, so you get pi*s^2/8. hope this helps! definitely memorize that and just remember if the cross sections are semi-circles, you use pi/8 as the coefficient. good luck!

@@turksvids thank you!

Thanks! Hope everyone gets the score they’re looking for!

keep in mind that this video is specifically about things my current students are still occasionally messing up. i expect basically all of them will get 5s pretty easily, so these are kind of objectively tricky things. there are probably 35-40 multiple choice per year that are quite straight forward if you know your stuff. the Riemann sum thing shows up on multiple choice sometimes (obviously, since i pulled examples from old tests), but it's never more than one question out of 45, so not a big deal. here's an explanation that i gave in another comment somewhere the other day about the semicircles (definitely just memorize it, though): (this assumes there are two curves bounding the region...) The diameter is in the plane, so the diameter would be s = (f(x)-g(x)) or (top - bottom). That makes the radius s/2. The area of a circle is pi*r^2, so pi*(s/2)^2 = pi*s^2/4.

@@turksvids I am also self studying so thats a downside. Anyways, I really wanted to thank you for your efforts. Wish you the best!

turns out i don't know how to do that so not this year...won't help you but going to consider it for next year, for sure! good luck on the exam!

definitely. actually don't simplify. it's risky and you get points once you get to where you got and then lose the point if you simplify wrong. it's like my worst habit when i make videos that i simplify all the time.

Related rates on the frq always feels more like chain rule to me. Shows up as part of the volume problem or the diff eq from time to time now. I have a playlist of related rates FRQs somewhere if you want to dig in. AB Calculus Related Rates Free Response Questions kzfaq.info/sun/PL6iwkLfBjZiye_FuKHypc8XpYXlyrvUF8

@@turksvids that is a good one iam not bad with that but will definitely check it I mean like cylinder and big volumes and stuff like a whole separate question for related rates will it come on this Monday frq?

I’d bet there won’t be, but they often surprise me.

@@turksvids thanks man wish me good luck man this exam is a very important switch in my academic life and thanks for your vids they are very helpful keep up the hardwork best of luck with the rest of your career

I wish you’d found my channel sooner, but I definitely recommend you start grinding FRQs: AP Calculus Free Response Questions kzfaq.info/sun/PLA83584C88AB6F0AE I have them sorted by topic into playlists if you look around on my channel as well.

@@turksvids Thank you so much! I'm gonna watch that now and start looking, I may come back later with more questions and seeking more advice lol :)

These are the videos I highlight as review worthy: AP Calculus Review Videos (Calc AB) kzfaq.info/sun/PL6iwkLfBjZiw2H9tmA1vW9a93_eJy6bLb

@@turksvids Okay so does watching every video tmrw at like 1.25x speed and working thru problems before you solve each of them sound like a good plan? And then after go to the FRQ videos and try to apply it conceptually? (I also have extreme adhd so its hard for me to focus but I gotta lock in)

Yup. Just make sure to note what the variable is.

if it's that then the bounds of the integral also have to work.

There’s a proof and all but I’d say in the next two days memorizing it seems like a better use of time. (Proof is really just the chain rule on g(f(x)) = x gives g’(f(x))*f’(x)=1 and say x=a so f(a)=b, g’(b)=1/f’(a) and you’re done)

That looks right to me!

​@@turksvids you sure cause there is someone who solved it to Me and got another answer

yeah, i'm pretty sure.

@@turksvids the thing that confused me that I get c=15 but if I raised it to e and added it to the other variable I won't get the same answer , we can't raise it to the power e ? Is it because it is not e^15?

fingers crossed for you if that's your goal!

...yeah, i've been around a while

nah, just part of my last name is turk!

@@turksvids alright! Also, thank you for your videos! I've been using all your videos to prepeare for this years AP Calc BC exam haha!

real

evet yerli malı oh oh

I hope you get whatever score you’re aiming for!

i guess that's one way to look at it

well that makes me sad...my students thought some of it was pretty clutch.

@@turksvids I was just salty because the FRQ was really hard lol. This was a very informative video! Don’t be upset
