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).

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.

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.)

My best script capital B was in fifth grade, my script has gone downhill ever since. I wanted to leave school that day because I knew that I would never recreate that capital B. This comment gives me hope, thanks! Also, good luck on your AP Calc exam!

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.

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
8 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.
