Thread: Double integrals problem - help appreciated

Hi, please look at the following problem:



I was asked to evaluate the above by considering the following:

D is the region enclosed by the triangle with vertices (1,1), (2,2) and (3,0)


I would appreciate any help in tackling this problem - many thanks in advance

What have you done?

A sketch would be a good start.

Yes, I sketched and found out that I need to add two separate integrals.

Good. Do you know the equations of the lines that form the triangle?
