Defining a Polar Graph
The steps for defining a polar graph are similar to the steps for defining a function graph. This
chapter assumes that you are familiar with Chapter 5: Function Graphing and Chapter 6:
Graph Tools. Chapter 8 details aspects of polar graphing that differ from function graphing.
