Find parametric equations for the part of sphere x^{2}+y^{2}+z^{2}=9 that lies between the planes y=1 and y=2.

2. Relevant equations

3. The attempt at a solution

Okay knowing that the p=3 I wrote the parametric equations for a sphere as

x=3sin[tex]\phi[/tex]cos[tex]\theta[/tex] y=3sin[tex]\phi[/tex]sin[tex]\theta[/tex]

z=3cos[tex]\phi[/tex] now the phi bound is 0<[tex]\phi[/tex]<[tex]\pi[/tex]

but I'm not sure what to write for the [tex]\theta[/tex] bound.
