Find the moments of inertia Ix, Iy, I0 for a lamina in the shape
of an isosceles right triangle with equal sides of length a if the
density at any point is proportional to the square of the distance
from the vertex opposite the hypotenuse. (Assume that the
coefficient of proportionality is k, and that the lamina lies in
the region bounded by x = 0, y = 0, and y = a-x).
