# KIM MALTMAN'S MINI-COURSE ON TRIG BASICS

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

OVERVIEW:

This section of Chapter 1

• 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.

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

BACKGROUND MATERIAL (AND LINKS):

For this section of the course you should be familiar with

• 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).
