Hello, I'm new to this forum so please bare with me if I post in the wrong section.

Anyhow, I'm stuck on this problem and I'm not sure exactly what to do ...

Integrate -> (1+e^tanx ) (sec x ) ^2 dx

I tried using u-sub method and i got this ..

let u = tan x

du = ( sec x ) ^2 dx

so I got that ( sec x ) ^2 dx cover, what about the 1 in front of e^tanx ?? What do I do to resolve the problem ??

Thanks in advance.
