Investigation 3 : Graphing Equations on Polar Paper

Step B

If you are having difficulty making a comparison between this graph and the graph of r = cos, ask yourself the following questions.

  • What are the centre and radius of this graph?
  • How does the size of this graph compare to the size of the previous graph?
  • Does the graph go through the origin?
  • Is the graph centred on the pole?
