How do you find sin(16x) and cos(4x), if you know that cot(8x) = -2 and 8x is an element of II? Thank you in advance!
#tan(2(4x))=tan 8x=(1-tan^2 4x)/(1+tan^2 4x)." But, "tan8x=-1/2.#

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.
