# How do you find the derivative of #(ln tan(x))^2#?

How? Use the chain rule -- twice. And simplify the answer. (Often simplifying is the tricky part.)

Therefore we can re-write the derivative using:

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
