All about Rate In-Rate Out AP Calculus FRQs

In this video we talk about all the types of things you'll have to do on the rate in-rate out AP Calculus Free Response Questions (FRQs). These types of questions come up often--17 times since 2000 as of 2021! You will have to know this for both the AP Calculus AB and AP Calculus BC exams.
Common concepts: identify a rate in context; integrate a rate and interpret the result; write an accumulation function; evaluate an accumulation function; determine increasing/decreasing at a point or on an interval; use an accumulation function to find a total; determine absolute maximum/minimum value and time at which it occurs (Candidates Test! Or Lonely critical point!); understand what happens when only one of the rates applies

10 billion times better than my math teacher. THANK YOU SO MUCH!

[@turksvids]

love to hear it (kind of...). Rate in/Rate out is a pretty common topic, so you definitely want to master it.

[@dpmike32819]

Thank You for all the time it took you to do all the research

[@turksvids]

Thanks!!! I just hope future exam takers will benefit from the effort!

[@turksvids]

Good luck!

Im trying to get a 5 for calc AB I feel confident, getting in lots of practice for key concepts in each unit after taking notes the hard part is juggling several APs but notes & practice is my best strategy

[@turksvids]

Good luck on all the exams! Hope my videos are helpful!

[@WarriorBane]

@@turksvids they sure are, I appreciate all the teachers who put effort into putting content online to reach more students🌏👍

[@laraterpetschnig]

Thank you so much! My teacher in class doesn't make much sense to me so this is really helpful.

[@turksvids]

Glad you found it helpful! Good luck on the exam!

[@shiv5702]

Do you have by chance a video explaining the main types of FRQ's on the AB test?

[@turksvids]

Unfortunately nothing that hits all the main types succinctly. I have the problems kind of grouped by type in playlists linked on this site: turksmathstuff.com/apreviewvids.html
Hope this helps!

[@shiv5702]

@@turksvids No problem, thanks so much! Appreciate how fast you responded though.

you are amazing thank you so much

[@turksvids]

Thanks for the comment! Good luck with your studies.

[@loreleiduarte8715]

should i expect this on the calculus AB AP exam?

[@turksvids]

There are a bunch of types that can show up and none of them are on it every single year, but this type has definitely been trendy for a while. I definitely recommend getting comfortable with it!

thanks
