I think I got 1/32 for that one.
I got 1/32 also. I had 8 lines of work for it.
What was the ans to the one with cos(0.001) or something? No calc mc
i put 1/51 for the inverse question, read it right before going into the exam
Hb when it gave the graph of f’ on frq and asked about inflection points, relative max and min, and intervals conc down and negative ?
Anyone remember that? -1,1,3 for inflection I think… Idk about relative extrem, and bounds were like (-2,1) or something i forget exactly and another one (basically when the f’ was decreasing and negstive
Yes, 88 was the awkward trapezoidal Riemann sum on MC
So I’m going to change my predictions for myself
MC No Calc: 21/28
MC With Calc: 16/17
MC:Total (37/45) x 1.2 =44.4=44
FRQ
FRQ #1 9
FRQ #2 9
FRQ #3 9
FRQ #4 4
FRQ #5 8
FRQ #6 5
FRQ Total:44
Raw Score:88/108
Im starting to feel that on the ap exam if you do all the work right but your answer is somehow off then they will just give credit…if everything else is right
@stoopidfoose I just picked the one that was a -sin graph because it looked like a definition of a derivative but it didn’t have the limit.
1/32, quotient rule madness!!!
i feel like those diff eq’s are gonna be worth a lot of points 
In the problem the fact that its 0.0001 or whatever means derivative. This is because the limit as h approaches 0 is kinda like saying an infinately small gap between two points and 0.0001 is really small so its kinda like a derivative
I understood fairly well. I realized most FRQs you can lose major points if you neglect to do so, so I hardcore reviewed that technique.
I know. I think the CB is starting to value Diff equation more because there were way more than normal of those type of problems on both the MC and the Free Response. The weird part was neither one of those FRQ’s had you solve for y like every other FRQ of that type does.
The cos (.001+x) thing was like taking the derivative as a close approximation to the derivative, so it was -sinx
for that johanna total dist I got 8100. I did absolute value of the one negative 220, added the right hands and multiplied by 10.
No. Not until the end of July/Beginning of August
@nhljohn871 the first dierivative must always be positive.
For the separation question, BC had it too and someone said you could have done a Taylor Series…
Would it be correct if you did the integrals sepretate? as in 30+ integral 0 to t R(t) - integral 0 to t D(t) =50?
