anonymous · Answer

the contents are enclosed in a square root

anonymous · Answer

that's it, how do i get to the answer ?

myininaya · Answer

$$\int\limits_{}^{}\frac{\sqrt{1+e^x}}{e^x} \cdot e^x dx \text{ let } e^x=\tan^2(u)$$
Haven't tried this yet but it might work

experimentx · Answer

i am looking for it too.

myininaya · Answer

I think will work actually 
After the sub and writing 
$$2\int\limits_{}^{}\sec^2(u) \csc(u) du$$ you will need to do integration by parts

myininaya · Answer

integration by parts just once
