Overview

Recall from a Pre-Calculus course polar equations (see Lesson Notes - Trigonometry - Polar Equations and Graphs but ignore any "text notes"). A polar equation, e.g. r=sin(3θ), can be converted to a rectangular equation, but some calculus operations may be simplified by working with the polar form. This lesson merely reviews and practices skills working with polar coordinates, polar equations, and polar curves from a Pre-Calculus course in preparation for doing calculus in polar coordinates in the next lesson.

Objectives

By the end of this topic you should know and be prepared to be tested on:

• 10.2.1 Convert polar equations <-> rectangular equations
• 10.2.2 Evaluate polar equations at specific angles
• 10.2.3 Find axis intercept points of polar curves
• 10.2.4 Graph a polar equation manually and/or electronically
• 10.2.5 Find collision points and self-intersection points on a polar curve manually and/or electronically
• 10.2.6 Find the intersection of two polar curves manually and/or electronically

Terminology

Define: polar equation, pole, collision point, self-intersection point
