# Math Help - Trigonometric substitution and Integrals

1. ## Trigonometric substitution and Integrals

I'm having a really hard time integrating:

∫ (e^(t))⋅(1+e^(2t))^(1/2)

I'm supposed to use Trig substitution to solve this and I'm not sure where to go from here.
Could someone please explain the steps?

try the substitution ...

$e^t = \tan{u}$
