Hello,

We were given the question below as an exercise but I am a bit confused and am in need of help.

Spherical coordinates (p, theta, phi) are defined by

x=pcos(theta)sin(phi)

y=psin(theta)sin(phi)

z=pcos(theta)

Compute Laplace's equation u_{xx}+ u_{yy}+ u_{zz}= 0 in spherical coordinates.

I would really appreciate any help.
