How the heck do I do this problem?

------

Evaluate integral:

$$\int\int$$e^(x/y) dA

Where dA=dxdy or dA=dydx

Region R is bounded by the graphs of y=2x, y=-x and y=4

Hey signature and welcome to PF,

I'm assuming that you haven't done any integration over regions before. If this is the case I'm afraid the best I can do is point you towards the relevant chapter in your course text. Double integrals are difficult enough to explain, even more so without proper diagrams.

If you have met double integrals before, what do you know about them? How do you evaluate them?
