Aplets and their views
Aplet views
This section examines the options and functionality of the
three main views for the Function, Polar, Parametric, and
Sequence aplets: Symbolic, Plot, and Numeric views.
About the Symbolic view
The Symbolic view is the defining view for the Function,
Parametric, Polar, and Sequence aplets. The other views
are derived from the symbolic expression.
You can create up to 10 different definitions for each
Function, Parametric, Polar, and Sequence aplet. You
can graph any of the relations (in the same aplet)
simultaneously by selecting them.
Defining an expression (Symbolic view)

Press or to
select an aplet.
The Function,
Parametric, Polar, and Sequence aplets start in the

(
CLEAR
).
Expressions are selected (check marked) on entry. To
deselect an expression, press

expressions are plotted.
