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.
