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

Yes...

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

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

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

turingtest · Answer

this would lead me to think that this cannot be represented in terms of elementary functions http://www.wolframalpha.com/input/?i=integral+x%2F%281%2Be*sinx%29dx 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!
