Please see the attached file for the full problem description.
2. Determine the values of the given integrals, where W is the region bounded by the two spheres x^2 + y^2 + z^2 = a^2 and x^2 + y^2 + z^2 = b^2, for 0< a <b.
: refer to integral 6.
This shows how to transform an integral from Cartesian to polar coordinates and determine the values of integrals in a region bounded by two spheres.
