f(theta)
1
Insert a polar graph into a question, answer, matching group, or
narrative.
To edit an existing graph, double-click the graph or click Format
from the menu bar and select Format Graph.
2
Click the Functions tab, select f(theta) from the drop-down
menu and click New.
3
Enter a function for r (the absolute distance from the point to the
origin) using theta (the angle, in radians moving
counterclockwise, from the horizontal axis) as the variable. The
example shows the function 4 * sin(theta * 3). Use the same
algorithmic syntax used to define variables.
NOTE
Variables can be used anywhere in the function
definition or as values for the domain.
Click the Add from List button next to the
function definition to display a list of currently
defined variables, constants, and keywords.
4
Enter the domain of theta. The default domain for functions of theta is from zero to 2 pi.
5
To display the function only if a certain condition is met, enter the condition in the field following Display function (only
if ).
6
To change the drawing style for the function, click the Pattern drop-down menu .
7
To change the color of the function, click the Color drop-down menu .
8
Click Apply to view your changes in the editing window or click OK to record your changes and close the New Function
– f(theta) window.
Point (r, theta)
1
Insert a polar graph into a question, answer, matching group, or
narrative.
To edit an existing graph, double-click the graph or click Format
from the menu bar and select Format Graph.
2
Click the Functions tab, select Point(r,theta) from the drop-
down menu and click New.
3
Enter the coordinate of the point in terms of r (the absolute
distance from the point to the origin) and theta (the angle, in
radians moving counterclockwise, from the horizontal axis).
NOTE
Variables can be used as values for r, theta, and
the label.
Values for r must be positive.
