[Maxima] Parameterization of implicit equation

[Bowo Prasetyo]

Thanks Barton and Adam,

I will learn the links.

And about the solve function in Maxima, it seems always give simple
parameterization first to x (= %r1) and y (= %r2), then solve for z.

For example if I change the degree of x and y to 1, and z to 3.. it
still gives x = %r1, y= %r2 and then solves z for 3 roots.

Thank you
