    Graphing Polar Equations

    What is the easiest method for graphing polar equations without using a calculator?

    Graph each polar equation.

    (1) r = 3

    (2) r = 1 + sin(theta)

    Plot points.

    Note that r = 3 is a circle of radius 3 centred on the origin. After some thught, it should be obvious why .....

    Plotting points in this case is very different than graphing functions on the xy-plane.
