I'm so glad your test went well! Thanks for supporting the channel.

Thank you so much! Extremely helpful. For Q90, if anyone wants a faster way of doing it, take the polar area integral of the circle from 0 to 2π and subtract it from the polar area integral with bounds of 0 to π for 2cos(3x).

Is there a reason that the period of 2cos(3x) is only pi?

I passed my calculus using your videos, CLEP calculus study guide, CLEP calculus books and online test. Thanks for the videos

Late but this guy is incredible! Turned my calculus year around later on with his frq and multiple choice practice, it was a huge help on the exam! Many thanks!

I am happy to hear that this helped for the AP exam! Best wishes with this upcoming school year!

For question 91 i just used trace from the calculator to trace the curve until it reached 3.14 to determine theta. And then integrated the polar curve from 0 to pi and subtracted from the area of the circle.

These are so helpful!!! Thanks a lot for doing them! Could you please do a lot of practice FRQs for Calc as well? They're pretty tricky and it would be great to see your thought process! Thanks again!

I am glad the videos are helpful! I am building up my frq content little by little. I completed the entire 2019 BC FRQ section and will definitely be making my way through the earlier years. Thanks for watching and good luck on your AP test!

Please tell me this exam is harder than usual😭 struggled

This test was trick! Do your best to study a bit more, sleep, then show up and put your best math on the paper. No matter the outcome, you are leveling up as a student! There is still plenty more work to do in college!

Is the 2012 exam still comparable to more recent exams?

@vinteachesmath

2 жыл бұрын

Yes, the curriculum has not changed much at all. The original AP exams (1960's) up until the early 90's have topics they no longer cover (epsilon-delta limits, Simpson's Method, trig substitution integrals, etc.)

I appreciate this so much

Can you please clarify why did you put r=2cos(3theta) = 0 in order the find the limit of the integral on number 91? Thank you

This helps us to find the bounds of one petal because that is where the petal passes through theta=0, which we then multiply by 3 to get the whole rose curve’s area.

Thank you so much, this has been really helpful! I just have a quick question about 82, why do we have to use that formula? Why can't we use f(b)-f(a)/b-a. Thank you so much!

For average value, you use the formula that he showed. The formula you are referencing is the average rate of change. Hope that helps :)

Good question! We would use your formula if they asked for the average rate of change. Average value or average function value uses the formula I wrote for 82.

For 88 will the double derivative always be concave up if the first derivative is increasing? For example option b is increasing for x

@vinteachesmath

7 ай бұрын

Yes, if you know the first derivative is increasing on some open interval, then f(x) is concave up on that interval, always. Yes to your second point, option B is no good because the function for f(x) is concave down on the entire given interval.

Just took it. It was rlly weird to me atleast
