1. The problem statement, all variables and given/known data Find teh center of mass of a thin infinite refion in the first quadrant bounded by the coordinate axes and the curve y=e-2x, if ρ(density)= xy 2. Relevant equations 3. The attempt at a solution I set M= ∫∫ xy dydx where y goes from 0 to y=e-2x, and x goes from 0 to infinity. I solved this and got 1/8 but when i try to calculate Mx and My the integration are impossible.
