Question

How do I integrate the following?
int_{0}^{1}int_{0}^{x} e^{y/x}dydx

I tried substituting the y/x part but didn't get very far :/

Answer 1

\[\int\limits_{0}^{1}\int\limits_{0}^{x} e^{y/x}dydx\]

Answer 2

\[\int e^{y/x}dy=xe^{y/x}+c\]

Answer 3

I managed to figure this out in the past while, but thanks anyway :)
