Table 1-6 Parametric Aplet Summary
Summary of Functionality View Name and Display
Press SYMB to return to this view at any time. The Parametric Symbolic View contains Parametric Symbolic View
definitions for up to ten parametric equations, each one defining x(t) and y(t) in terms of t.
The menu items are the same as the Function Symbolic view, except here T replaces X as a
typing aid.
Press PLOT to enter the Parametric Plot view. This view displays the graphs of parametric Parametric Plot View
equations defined in the Symbolic view. The functionality here is the same as in the Function
Plot view, except that the FCN functions do not apply here.
Press SHIFT followed by PLOT to enter the Parametric Plot Setup. This view is similar to the Parametric Plot Setup Page 1
Function Plot Setup, except that it contains TRNG and TSTEP to control the t-values used to
generate the (x,y) ordered pairs for graphing.
