Question

Integral x/ (1+esinx) ....from 0 to pie/2

Answer 1

Is this your question
\[\int_{0}^{\pi/2} \frac{x}{1+e^x \sin x} dx \]
?

Answer 2

Yes...

Answer 3

wolf won't do the indefininite, and gives some random-looking decimal for the answer to the definite

Answer 4

Oh wait...I just checked the question again...its just "e" . Not e^x .

Answer 5

doesn't seem to help much
wolf still refuses to help

Answer 6

this would lead me to think that this cannot be represented in terms of elementary functions

though perhaps for the definite we can shift the bounds somehow, and use some even-odd properties to handle it
I have to get to class, good luck!

Answer 7

Ok...thanks! :)
