Can’t afford a ti-89?  Get a free graphing calculator with Google.  That’s right.  Google is now a free graphing calculator.

Multiple Graph

gg3

You can display multiple functions on one graph.  Hovering the mouse over the graph will give you the trace and display the x and y coordinates.  The navigation is the same as Google Maps.  You can zoom in, zoom out, and pan.

Multiple Variables

gg2

Google can also graph a two variable function, and display graph in 3D.  It displays a cool animation of the graph spinning around in 3D.  Again you can zoom in, zoom out, and pan.  This feature requires that your web browser supports WebGL, which it probably does.
