Hi everybody,

I want to plot a function f(x,y). I know I can do this with plot3d(f(x,y),x=-1..1,y=-1..1) and this works. But now I want to do something else: x and y fulfill g(x,y)=0 and I want to create a new function h(x) that is basically the old function f(x,y) except that for each x he has to take the y so that g(x,y)=0. Then I can do plot(h(x),x=-1..1). 

OK, this is easy if g(x,y)=0 can be solved for y. But life ain't simple ;-) and in my example this is impossible. I hope anybody has an idea?

Regards,
