(2)Input the following expressions and values: xt = cos(t), yt = sin(t), tmin = 0, tmax = 360

(3)Tap [OK].

This displays a parametric equation graph as shown here.

Tip

You can display equations such as (x(t), y(t)) on the Geometry window by dragging the equation and dropping it into the Main or eActivity window. When you do, however, the equation appears as text (it does not graph the equation).
