#### Activity Overview

This activity, which acts as a learning review, gives the solution for the first seven questions of the MM CAS 2002 Exam 1 Part 1. Students use the Derive™ software to solve problems on trigonometric functions.

#### Before the Activity

• Install the Derive™ 6 software on the computer
• See the attached PDF / DFW file for solutions to the questions, and print the file for the class
• #### During the Activity

Distribute the printed pages to the class.

In this activity, students will:

• Find the nature of the trigonometric graph and find its period
• Identify the factor by which a trigonometric graph has been dilated
• Find the maximum value of a graph
• Understand that the graph of y = f(x) corresponds to y = f(-x) reflected along the y-axis
• #### After the Activity

Review student results:

• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
