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)
Choose the aplet from the Aplet Library.

an aplet.
The Function,
Parametric, Polar, and
Sequence aplets start in the Symbolic view.
If the highlight is on an existing expression, scroll to an
empty line—unless you don’t mind writing over the
expression—or, clear one line (fPErl) or all lines
([SHIFTlCZ.£/tj?).
Expressions are selected (check marked) on entry. To
