The
Smart Graph
feature graphs the requested
expressions/ functions using the current graphing
mode.
Expressions entered using the
Graph
or
Table
commands are assigned increasing function
numbers starting with 1. They can be modified or
individually deleted using the edit functions available
when the table is displayed by pressing
† Header
.
The currently selected Y= functions are ignored.
If you omit an optional
var
argument,
Graph
uses
the independent variable of the current graphing
mode.
Note: Not all optional arguments are valid in all
modes because you can never have all four
arguments at the same time.
In function graphing mode and
ZoomStd
window:
Graph 1.25aù cos(a),a
¸
In parametric graphing mode and
ZoomStd
window:
Graph
