How do I plot a 3D graph on an interval?
Answered
I want to plot some function of x and y where 0<x<1. (The function exists everywhere, but this is the only interval I need)
Here's what I've tried:
 if ( 0<x<1, f(x,y) )
 if (0 < x , if (x < 1 , f(x,y) ) )
 a(x, y) = if (0 < x , f(x,y) ) and then b(x, y) = if (x< 1 , a(x,y) )
Result is the same every time: no plot at all. Independent from f(x, y).
Please correct me if I'm doing something wrong or just explain how to do this.

This seems to be working here:
See the file with further restrictions on y, too
Uh, I missed a thing.
If you have already defined a function f(x,y), use just f in the If command:
