Mass, Centroid, and Moments

Compute the mass, centroid, and moments Ix, Iy and Io of the half-disk:
y>0, x^2+y^2<1
with density delta(x,y)=y

it is said we should know the primitive (sin(x))^n
or (cos(x))^n from Pi/2 to 0

Solution Summary

This shows how to compute the mass, centroid, and moments Ix, Iy and Io of the given half-disk.
