PARAMETRIC EQUATIONS Graphing Plane Curves (Page 6 of 12)

To evaluate the parametric equations at any value of t within the current domain (between Tmin and Tmax), use the CALC value command. Enter the desired value of t, and the values of both x and y are displayed along with the location of the point corresponding to those values.

Let's evaluate the parametric equations at t = π.

 2nd CALC key. 1: menu selection. 2nd Pi key. ENTER key. Calculator screen image.
