(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The following is an equation of a 3-d surface in spherical co-ordinates.

r = f(theta,phi) = sin(theta)

Plot it on 3-d space.

2. Relevant equations

r = [tex]\sqrt{x^2 + y^2 + z^2 }[/tex]

theta = arccos (z/ [tex]\sqrt{x^2 + y^2 + z^2 }[/tex])

3. The attempt at a solution

I converted the equation of the surface into cartesian co-ordinates , and got the following equation of a 3-d surface

(x^2 + y^2 + z^2)^2 = (x^2 + y^2)

is the above equation in cartesian co-ordinates right ?

and is it a right approach to plot it?

I think the plot is as shown in image given below ,

but how to arrive at the plot given below I am unable to think.Please help
