## Graphing Functions

To graph a function, first create a graph window by pressing ⌘-g. Then press the + button in the Functions window to bring up the Add Function menu:

Then click a function type to graph.

Let’s graph the 2D function **sin(x)**:

Here’s a 2D parametric equation, x = sin(t), y = cos(t). Press **control-g** to bring up the grid.

The 3D equation f(x, y) = x * y:

The 3D parametric equation: x = sin(t) * 4, y = cos(t) * 4, z = t / 10.

## Switching Between 2D and 3D Modes

Double-click on a 2D function to switch the grapher to 2D mode, and double-click a 3D function to switch the grapher to 3D mode.
