## Homework Statement

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

## Homework Equations

## 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 M

_{x}and M

_{y}the integration are impossible.
