Three-dimensional graph

Graph of the function f(x, y) = sin(x²)*cos(y²).

A three-dimensional graph is the graph of a function of two variables f(x, y).

Provided that x, y, and f(x, y) are real numbers, the graph can be represented as a planar or curved surface in a three-dimensional Cartesian coordinate system.

Example

The graph of the trigonometric function on the real line

is

.

If this set is plotted on a three dimensional Cartesian coordinate system, the result is a surface (see figure).
