By the end of this section, students will be able to identify and graph polar equations.

By the end of this section, students will be able to identify and graph polar equations.

### Graphing Polar Equations(you do not have to do this by hand on a quiz/exam, just one on the hw)

Many of these equations are difficult to transform into Cartesian form, this one is easy

By the end of this section, students will be able to identify and graph polar equations.
