GRAPHING FUNCTIONS
5. Polar Coordinate Graphs
A polar coordinate graph shows coordinates with distance r from the origin point and
positive-value angle
θ
from the X axis.
When the polar coordinate graph mode is selected, pressing
enters the value of
θ
.
<Example>
To draw a polar coordinate graph of cos
θ
:
1. Set to the polar coordinate graph mode
Press
Ï
E
3
.
2. Entering equations.
In the polar coordinate graph mode, the equation input
screen (press
) allows a maximum of six
equations (R1 to R6) to be entered.
When
is pressed, the cursor pointer positioned at [R1].
Enter the equation.
Press

.
3. Drawing graphs.
Press
. A small oval graph appears on the display,
as shown on the right.
The oval graph results because the display pitches of
the X and Y axes are not the same.
(The default X and Y range settings are valid for an initial graph display.)
