Homework Statement

Find the antiderivative of $$\frac{1}{\sin\alpha}$$

The Attempt at a Solution

Ugh, maybe it's just a temporary brainfreeze, but I have no idea how to go about it.

Try rewriting the sine in terms of exponential functions. After a change of variables and partial fractions you should be able to integrate it.

Find the antiderivative of $$\frac{1}{\sin\alpha}$$

Maybe if you write that as $${\csc\alpha}$$ it will look more familiar.

$$\frac{1}{\sin x} = \frac{\sin x}{1-\cos^2 x}$$
