I do not understand your equations. r should be a function of theta
and if theta were a single value (e.g., 1) there would be only a
single point. Also, what is the ^.= in the equations?
Clear[r]
r[theta_] = theta (1 - theta^2);
PolarPlot[r[theta], {theta, -1, 1}]
PolarPlot[r[theta], {theta, -1, 1},
PlotStyle -> Red,
PolarAxes -> Automatic,
PolarGridLines -> {
Range[0, 2 Pi, Pi/4],
Range[0.1, 0.3, 0.1]},
PolarTicks -> {"Degrees", Automatic},
GridLinesStyle -> LightGray]
