Find the parametric representation for the surface:(adsbygoogle = window.adsbygoogle || []).push({});

The part of the sphere x^2 + y^2 + z^2 = 16 that lies between the planes z = -2 and z = 2.

okay, i know that i have to use spherical coordinates which is

x = 4sin(phi)cos(theta)

y = 4sin(phi)sin(phi)

z = 4cos(phi)

i know how to find the interval for phi, but how do you find the interval for theta? this is probably a stupid question, but i don't get it.

thanks!
