## 3D surface visualization.

Write a math function f(x, y) with two variables x, y and visualize the surface graph.

The surface is visualized in the 3 dimenssional space x, y, and z. z = f(x, y).

Use ^ to raise to any power.

Use log(number/x, base) for logarithm, you can omit the base for log to base 10.

Use sqrt(x) for squre root.

The rest of the mathmatical notations/symbols are the same as the general conventions.

x Axis From Interval To

y Axis From Interval To

F(x, y)
