Overview

Today's material is calculator intensive. We will learn about breaking degrees into smaller units, evaluating trig functions on a calculator, and finding the angle given the trig ratio. Have your calculator (handheld or software) at hand!

Objectives

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

• 2.2.1 Add/subtract DMS (algebraically and electronically)
• 2.2.2 Convert DMS decimal degrees (algebraically and electronically)
• 2.2.3 Evaluate trig functions on a calculator
• 2.2.4 Proper notation for inverse trig functions
• 2.2.5 Evaluate inverse trig functions on a calculator

Terminology

Define: degree, minute, second, DMS vs. decimal degrees

Supplemental Resources

You must be able to use a calculator (handheld or software) to do many of the processes covered in this lesson. If you have a handheld graphing calculator then these sites may help:
