Polar Coordinates

Objectives

In this lesson, you will learn to:

• Plot polar coordinates on a polar plane.
• Find multiple representations of a point in the polar plane, including positive and negative values of r.
• Convert coordinates and equations from rectangular form to polar form and from polar form to rectangular form.
• Sketch the graphs and write the equations of roses, lemniscates, limacons, and other polar equations.
• Express complex numbers in polar form.
• Evaluate expressions involving multiplication, division, and powers of complex numbers in polar form.
