10.2 Graphing Polar Equations Day 1. This is a picture of what a polar grid looks like. Notice the “famous angles” are illustrated for us. The concentric circles represent the values of r. Today we will be graphing polar equations using a table of values.

This is a picture of what a polar grid looks like. • Notice the “famous angles” are illustrated for us. • The concentric circles represent the values of r. • Today we will be graphing polar equations using a table of values. • Your calculator will be much needed! • (Remember to put your calculator in RADIAN mode and round to the nearest tenth.) • If your calculator says • “1.2E–12” or something like it, it means 0 • “Domain error,” it means undefined.
