How to sketch a function F(x,y)

[ptc-5137806]

Hello everyone.

I have to sketch this distribution function, but it always ends with this error:

It says that "y" is undefined.

Thanks in advance

Please attach a worksheet (upper right, "Use advanced editor"),

You have a 3D-function (2 independent x,y, 1 dependent variable F) but try to do a 2D plot - use a surface plot.

Not sure if your distribution function is defined correctly. Could imagine that you have something like G(x,y) in mind, but then, I may be wrong.
