# Math Help - Integation, possibly half angle

1. ## Integation, possibly half angle

I've been trying to do this for quite a while now and keep going around in circles, anyone offer help?

$\int\frac{1+tanx}{1+cosx}dx$

This has been aswered somewhere recently, but

$\int\frac{1+\tan(x)}{1+\cos(x)}dx=\int\bigg[\frac{1}{1+\cos(x)}+\frac{\sin(x)}{\cos(x)(\cos(x) +1)}\bigg]dx$

Can you take it from there?
