How do I find sin^-1(x).

I believe it would be chain rule but am confused on how to find it.

I am confused on what happens when you include the arcsin or arccos.

These are the questions I am dealing with but I just want it explained in a way that if the problems arent exactly like this I can solve them still.

(e) (2 points) Use the triangle in the previous part to write 3." in terms of 3:. This is the derivative of tan'1(a:)! (f) (3 points) Find the derivative of tan1(). 4. (6 points) Repeat the steps of the previous problem to nd the derivative of sin1LT)
