i have a question concerning transforming triple integrals into spherical coordinates. the problem is, i do not know how to find the limits of phi. Can anyone help me? Thanks...

Phi is the variable indicating the angle subtended from the positive z-axis to the negative z-axis. It is similar to theta which is usually defined from positive x, but all the way around to positive x again.

Phi is usually integrated from 0 to Pi/2 for the top four octants, and Pi/2 to Pi for the bottom four octants. Anything more than that and we'd need a problem.
