**1. Homework Statement**

I would just like some help on how to find the integral of:

sin(x) / cos(x)^2

**2. Homework Equations**

integration by parts?

uv-integral of v(du)

**3. The Attempt at a Solution**

I tried using integration of parts with u = cos(x)^2 and dv = sin(x) but I just got myself in a bigger mess.

I noticed that sin(x) / cos(x)^2 was equal to tan(x)sec(x). Not sure if that helps though...

Help please?!
