This lesson involves a brief introduction to the polar coordinate system.

This lesson involves a brief introduction to the polar coordinate system.
As a result, students will:

• Determine the location (quadrant) of various points given in polar form.
• Recognize cases in which a point lies on an axis.
• Convert points between polar and rectangular form.
• Discover that the polar coordinates for a point are not unique.
• Sketch the graphs of polar equations.
• Use their calculators to check graphs sketched using paper and pencil.

*Note: This activity contains an optional AP Practice Questions document for those students preparing for the AP Precalculus Exam.
