### 10.2 Graphing Polar EquationsDay 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.
• 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.
