The Graph O $$r = a \theta$$ In Polar Coordinates Is an Example of the Spiral of Is

The graph o $$r = a \theta$$ in polar coordinates is an example of the spiral of Archimedes. With your calculator set to radian
mode, use the given value of a and interval of  to graph the spiral in the window specified.
- $a = - 0.5 , - \pi \leq \theta \leq 4 \pi , [ - 6,6 ]$ by $[ - 6,6 ]$
