I do not have plans to include this problem in the test, but it's a good problem to look at nonetheless. You don't even have to know the inverse function to take its derivative: A problem that uses this theorem is Problem 29 on page Which brings us to the derivatives of inverse trig functions.

This is the real application of implicit differentiation in this chapter. In the long run, you will best be served by knowing the derivation of the inverse trig rules rather than memorizing the formulas.

You should learn the proofs of these formulas in the book on pp. Also knowing how to apply the inverse trig derivatives is important -- check out the examples in section 4. My treatment of the inverse trig derivatives in class was more comprehensive than I expect you to be responsible for.

## Cofunctions: Definition & Examples

Now, let's use the third step within our strategy list. We need to get a common denominator. The common denominator is cos x. This means we need to multiply the leftmost fraction's numerator and denominator by cos x, like so. Since there is a common denominator, the two numerators can now be added. If we take a look at the numerator, we can see it matches the left side of the first Pythagorean Identity.

### Cofunction Identities

Substituting, we get this. This last fraction can be simplified one more time. Looking at the first inverse relation, we can see that it is equal to sec x. In this section, we use graphs of sine and cosine functions to visualize their properties.
