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.
