Graph functions of the style f(x,y): 3D Function Grapher

Let me know of any interesting functions you find!

Hi MathsIsFun,

The page is eminently likable. The different features and the graphics make the page thoroughly interesting.

In my opinion, many functions are covered and none important are left.

I checked the graph with Trigonometric and Exponential functions. It works well.

I haven't come across any bug.

Hi;

Tried these

y^2 - x^2

1/(x^2 + y^2)

sin(x*180/pi)-cos(y*180/pi)

sin(x)*cos(y)

All looked okay. Very nice!

Thanks everyone!

I will check out IE (why is it always the exception?)
