Calculus AB Midterm Review

13:00 problem #7 the solution 1/6 is actually C but it's just cut out of frame, so the answer is not actually E

Answer to number 8 is actually 4, split up the problem to (3x/x) + (sinx/x), you will see that (3x/x) simplifies to 3 and (sinx/x) simplifies to 1 after applying the limit. Therefore, 3 + 1 = 4.

Talking hands math I don't know if you're a teacher or what but thank you for posting this!!
Just took my exam and feel super confident.

for number 28 should the answer be C due to the double angle identities for trig? Just wondering? Thank you for the video by the way.

Shouldn't #39 be =-1 since you need to find the normal line?

[gabrielshapirocalculus]

Here's the thing about #8: how do you what the derivative of sin(x) is? You have to first know the limit of sin(x)/x as x approaches zero in order to know what the derivative of sin(x) is, so using l'Hospital's rule is almost circular reasoning...and in #28 the answer is C (you could've rewritten sin^2(t)-cos^2(t) as -cos(2t) by the double angle identity for cosine).

#13 i thought we should look at the the limit from left of 1 and right of 1, since we got number/0. could you explain? thanks by the way for the video.

Answer to 35 is not 1/3 it is 1 since they are asking dx/dt not dy/dt

[connorcull]

39 should be -1 because it’s normal line, not tangent. right?

[redj_dev]

On number 26 you skipped doing the chain rule? I think

[alexx]

Isn't 25 none of these because its just csc not csc squared? 37:40

bro got so many of the questions wrong
