The way we read this question is that you go from spherical coordinates: p, theta, phi to cartesian x y z

r= sqrt(x2 + y2 + z2)
theta= arctan(y/x)
phi= arccos(z/r)

I can do the partial derivatives of r and theta, but phi is getting too complex.

This makes me wonder, are we reading the question correctly? and if so can someone work and show the work of the 3 partial derivatives of phi? I can do the matrix of the 9 partial dervs
