**CHAPTER 1, SECTION C:**
*RADIANS AND DEGREES AS UNITS OF ANGULAR
MEASURE (AND HOW TO CONVERT FROM ONE TO THE OTHER)
*

- discusses the common basic units
(radians and degrees) used in assigning number (angles) to directions
in the
*xy*-plane; and - reminds you how to go about (i) converting an angle given to you in radians into degrees and (ii) converting an angle given to you in degrees into radians.
- the motivation for using numbers (angles) to specify directions in the plane (reviewable by reading (or re-reading) Section (a), of Chapter 1 of the course); and
*the geometrical meaning of angles and angular measure, as well as the basic conventions used in assigning an angle to a given direction in the plane (reviewable by reading (or re-reading) Section (b), of Chapter 1 of the course).*

**OVERVIEW:**

This section of Chapter 1

Some motivation for why radians are preferred over degrees in most university mathematics courses is also given.
