(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Use substitution to evaluate the integral.

[tex]\int \frac{4cos(t)}{(2+sin(t))^2}dt [/tex]

2. Relevant equations

None, really.

3. The attempt at a solution

I'm not sure what to use as u, for the substitution. I've tried [tex](2+sin(t))^2[/tex], as well as other attempts, but I can't seem to find anything.
