SUMMARY
The discussion focuses on calculating the center of mass for a thin infinite region in the first quadrant, bounded by the coordinate axes and the curve y=e-2x, with a density function of ρ(x,y) = xy. The mass M was computed using the double integral M = ∫∫ xy dydx, resulting in M = 1/32 after proper integration. The participants emphasized the necessity of correctly setting up the integrals for Mx and My, suggesting the addition of an extra variable in the integrand to facilitate the calculations.
