Press **[MENU]**→Graph Type→Parametric to switch to parametric graphing mode. Alternatively, move to the entry line and press **[CTRL][MENU]**→Parametric. Next, follow these steps:

Type the

*x*-component equation, using*t*as the independent variable.TI-Nspire uses the notation

*x1*(*t*) for the first*x*-component,*x2*(*t*) for the second*x*-component, and so on.Type the

*y*-component equation, using*t*as the independent variable.TI-Nspire uses the notation

*y1*(*t*) for the first*y*-component,*y2*(*t*) for the second*y*-component, and so on.Edit the interval for the variable

*t*and the*tstep*increment.By default, parametric graphing is configured in radians with

Press [ENTER] to graph the parametric curve.

Here is an example of a parametric graph.

In the second screen, pressing **[CTRL][****G]** hides the entry line.

The third screen uses Graph Trace (press **[MENU]**→Trace→Graph Trace) to trace along the graph. Each time you press

or

the trace moves by a value of *t* equal to *t*-step.

Many of the features of function graphing (for example, changing attributes, adding a function table, or adding geometric objects to a parametric graph) are available in parametric graphing mode.
