To determine dy/dx for y = (cosx)^π, you use the chain rule. First, differentiate the outer function, which is (cosx)^π with respect to x. Then, multiply by the derivative of the inner function, which is the derivative of cosx with respect to x. The derivative of (cosx)^π with respect to x is -(πsinx)(cosx)^(π-1).

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.
