In this video we cover five issues that my Calc AB and BC students had this week while we reviewed for the AP Calculus exam.
1) Tangent line to a curve given the differential equation.
2) Solving separable differential equations (very common on FRQs!)
3) Find the second derivative from an implicitly defined derivative. (dH/dt = H+6, etc.)
4) Finding m and b if y = mx+b is a solution to a differential equation. This is always one to look out for. Not hard, but if you’ve never done it, the process is mysterious. I use both equating coefficients and taking advantage of concavity.
5) Related rates problems that are really just chain rule problems.
I hope you find this quick review questions helpful and good luck on the AP Exam!

![Solving Trig Equations by Equating Arguments
In this video we solve some basic trig equations that have sine and cosine on both sides of the equal sign. The method we use is to manipulate one side until you either have sine on both sides or cosine on both sides, then we just equate the arguments. There are a lot of skills we have to use to be successful here:
1) Finding coterminal angles
2) Cofunction identities
3) ASTC to find signs and reference angles in different quadrants
4) The Unit Circle and what it tells us.
