Investigation 3 : Graphing Equations on Polar Paper

Step A

• Be sure to plot the points in the correct form (r, ).
• The graph of the points given in the table should form a circle. 
• When the table is extended as instructed, the new points to be plotted are already on the circle.
• The circle should pass through the origin and be centred on the pole.
• What are the centre and radius of the circle?
