Enter a function f1(θ) in the text input field
marked "r=f1(θ)="
(Example:f1(t)=1-sin t)
Click the "Graph" button
(this button also refreshes the graph)
To see two functions graphed simultaneously:
Enter the second function
f2(t) in the text input field
marked "r=f2(θ)="
Click (to its "on" state) the check box next
to this input field
Click the "Graph" button
(Example:f1(t)=1-sin t,
f2(t)=cos 2t)
Up to 5 functions can be graphed simultaneously
To remove a function from the graph, click (to its "off" state)
the check box next to the associated text input fields and click
the "Graph" button to refresh
To erase the graph and all input fields, click the
"Clear" button
The angle θ ranges from
θmin.π to
θmax.π, measured in radians.
The values of θmin and
θmax can be changed
(in increments of 0.1) by clicking the
"+" and "-"
buttons under the fields marked
"θmin=" and
"θmax=".
Holding the buttons down causes the action to repeat.
