Graph expression1[, expression2] [, var1] [, var2]
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
¸
Some valid variations of this instruction are:
Function graphing Graph expr , x
Parametric graphing Graph xExpr , yExpr , t
Polar graphing Graph expr , q
Sequence graphing Not allowed.
3D graphing Graph expr , x , y
Diff Equations graphing Not allowed.
Note: Use ClrGraph to clear these functions,
or go to the Y= Editor to re-enable the system
Y= functions.
In 3D graphing mode:
Graph (v^2 ì w^2)/4,v,w ¸
