Chapter 4: Graphing Features
2. Graph Modes
• This calculator has two graph modes, rectangular coordinate
graph and parametric coordinate graph.
• To select the mode, press
@
;
to enter the SETUP
mode.
To set the rectangular coordinate graph mode. (default)
1. Press
@
;
to display the SETUP screen.
2. Press
E
and
1
.
The graph mode is set to the rectangular coordinate system.
To set the parametric coordinate graph mode.
1. Press
@
;
.
2. Press
E
and
2
.
The graph mode is set to the parametric coordinate system.
3. Explanations of Various Graphing Keys
Y
:
Displays the Graph Equation window. Up to 10 equations can be
entered in rectangular coordinate graph mode, and UP to 12
equations can be entered in parametric coordinate graph mode.
After the graph expression is entered, press
E
to store the
equation.
=
:
The expression can be represented as a graph.
= :
The expression cannot be drawn as a graph.
• Move the cursor pointer to the “=” sign and press
E
to
change between to-draw and not-to-draw.
Note:
To switch the window back to the calculation screen, simply press
the
#
key.
G
:
Draws a full-screen graph based on the equation(s) entered in the
Graph Equation window. To cancel the graph drawing, press
O
.
Note:
If no equations are entered in the Graph equation window, only
the vertical (Y) and horizontal (X) axis will be displayed upon
pressing the
G
key.
