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 time,2cos(time)/time,time ¸
