hello i'm learning about spherical coordinates and I was wondering how projections onto a plane work.
it seems that, to project a point in 3d space onto the xy plane, you just set z=0. is that right?

and also is there a way to turn a function f(x,y,z) whose graph is a surface in 3d (for example z=x^2+y^2) into a function g(x,y) whose points (x,y) are all projections of the points (x,y,z) of f onto the xy plane?
