Course: Trigonometry
Topic: Right Triangle Trigonometry
Subtopic: Calculators

Overview

Today's material is calculator intensive. We will learn about using a calculator or calculating software to convert between angle measures, evaluate trig functions on a calculator, and find 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:

• 2.2.2 Convert DMS decimal degrees 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

Terms you should be able to define: degree, minute, second, DMS vs. decimal degrees, inverse function, inverse trigonometric function
