Lesson: Graphing Polar Curves Mathematics • 12th Grade

In this lesson, we will learn how to plot and draw graphs of equations in polar form and how to identify classical shapes in polar form such as circles, cardioids, and roses.

Lesson Plan

Students will be able to

identify the equations and graphs of and sketch the graphs of special types of polar graphs,
sketch the graphs of polar equations by
- plotting points,
- using symmetry,
identify and find maximum and minimum -values from polar equations,
identify or describe the polar equation of a given special type of polar graph,
apply this knowledge to real-world problems to find polar equations representing, or sketch polar graphs of, a real-life phenomenon.
