This equation of a sphere in spherical coordinate form:(adsbygoogle = window.adsbygoogle || []).push({});

ρ = 4sinφcosθ converts very readily to (x-2)^{2}+ y^{2}+ z^{2}= 4 with very little effort.

Now this similar equation looks to me like it should also be a sphere, but I can't seem to get anywhere with it:

ρ = 4sinθcosφ

I just end up with a very ugly

x^{2}+ y^{2}+ z^{2}= 4yz/(√(x^{2}+y^{2})

and I have no idea what to do with that.

Is this a dead end? Is the second equation not a sphere?
