The final exam is March 14-17!
This is for discussing assignments from WEEKS 12-13, including homework, FINAL EXAM REVIEW, in-class
work or lessons, or anything else related to the
class from these weeks. Please be sure to include your
name at the end of your post for credit. When answering a question, DO
NOT GIVE SOLUTIONS! Provide hints or explain a method that you used, but
do not give the final result. As always, RESPECT IS A MUST! Anyone
abusing this forum will be banned from future use (meaning, no extra
credit!!!).
On the final, will there be a lot of sequences and series because it's a large portion of the AP.

Sequences and series are not on the final exam
DeleteWould anyone be up for a group study?
ReplyDeleteRachel
Guess not...at least tomorrow is Pi Day!
DeleteWhen using the integral test on a series can you just say that it's less than the sum of 1/k^2 (which converges) so therefore it converges as well? Or do you need to show more work?
ReplyDeleteHope
Yes, you can say that.
DeleteHow do you find d^2y/dx^2 (the second derivative) for parametric functions?
ReplyDeleteFind dy/dx (which is dy/dt divided by dx/dt). Differentiate dy/dx with respect to time. Then divide by dx/dt.
DeleteWhat will the breakdown be of topics from 1st tri vs. 2nd tri? Or, is it more a reflection of an AP test without sequences/series?
ReplyDeleteCumulative.
DeleteIn order to get a function out of parametric mode, can you solve for t using one equation then plug that answer in to the other other equation?

Yes, that is one way. We did examples in class of that idea, called eliminating the parameter.
DeleteDo we have to know trig identities (ex. cos2x or sin^2x) or will these be on calculator sections?
ReplyDeleteI remember Mr. Wilson saying to know those since they come up on both sections (non-calculator and calculator).
DeleteYou MUST know the power reducing identities for sine and cosine!
DeleteSo i'm going over solids of revolution and I'm still having trouble discerning when you switch the function to dy/dt instead of dx/dt. Any tips? Sorry it's so late 😁
ReplyDeleteIf you are using washers then you want the slices to be perpendicular to the axis you are revolving around. When you use shells you want the slices to be parallel. So, if this is not true for the method you are using, then you need to use dy to make it true.
