Parametric Functions

This video uses the TI83/TI84 calculator. The TI Nspire will accomplish the same results, but you must access some functions in different places:

- To graph a parametric function, go to the graphing window and press MENU, then GRAPH ENTRY/EDIT, then PARAMETRIC.

- To adjust the t values for a parametric function, use the graph entry window (the same screen where you enter the equations).

- Remember that to get an equal scale on both axes, you'll set up a window in a manner such that the ratio of horizontal distances to vertical distances is 4:3.
