This applet enables one to graph polar curves.
We are assuming that the curve is
given by r = f(t), where
r is the radius vector and f(t) is a function of the angle t.
The angle t varies from t initial to t final.
The computer will display the curve by plotting it at
number of points points and then connecting
these points by straight lines.
Clicking on the button Plot
will produce the graph of the specified
curve.
The Constrained/Unconstrained
button toggles between the two modes; it controls the scaling of
graph.
The current x and y coordinates of the mouse are displayed in the blue box
in the lower left corner of the applet.
