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 .....

Graph each polar equation.

(1) $r = 3$

(2) $r = 1 + \sin\theta$
Try looking at this site: Graphing Polar Equations

It should be helpful.

4. points....

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