After converting a surface over the region that $$\rho$$=sin$$\phi$$cos$$\theta$$/a + sin$$\phi$$sin$$\theta$$/b + cos$$\phi$$/c
I also have that this region is equal to 1.

I cant seem to get anywhere..

Well, $\rho$ can't be less than 0. What is the maximum value of $\rho$?

Moneyjane,

Could you show your work to get to the maximum of 1 ?

Thanks
