Activity Overview
This activity will help students identify the amplitude, period and shifts of graphs of sine and cosine using the TI-Navigator™.
Before the Activity
After the students have logged onto TI-Navigator and the teacher should go in to activity center. Use sin_graph.act to have the correct viewing window. Plot y = sin(x) or y = cos(x). To graph these by hand I use [0, 2pi], one period.
During the Activity
Ask the students these questions. They should be able construct an equation and graph it based on the information that the teacher gives. After information has been given out, each student should plot what he thinks is the right answer. After all students have contributed their answer, the teacher should graph the correct answer.
After the Activity
After the activity, use this LearningCheck™ quiz.
