Calculate the double integral:

x/(x^2 + y^2)dA, R = [1,2] x [0,1].

I'm not sure how to iterate this integral and proceed onwards. Any ideas?

Thanks in advance.

This is quite straightforward, it's just

The inner integral is easy to solve and the remaining integral can be tackled by simple partial integration. (See my signature.)
