b) Evaluate the integral Solution The following describes the region in spherical coordinates: The angle with respect to the z-axis, (I think it is phi, but I might have it mixed up with theta) goes from 0 to pi/6 The radius, rho, goes from 1 to 3. The angle with respect to the x-axis (I think theta) goes from 0 to 2pi Set up the triple integral with the limits above and you are integrating rho^2 (sin phi) d theta d phi may this will help u thank u very much i can solve completely but it doesn\'t work in xm.
