Three-dimensional graph

Three-dimensional graph

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 of curved surface in a three-dimensional Cartesian coordinate system.

Example

The graph of the trigonometric function on the real line: "f(x, y) = sin(x2)·cos(y2)"is: {("x", "y", sin(x2)·cos(y2)) : "x" is a real number}.If this set is plotted on a three dimensional Cartesian coordinate system, the result is a surface (see figure).
