Investigating Sine and Cosine Functions Graphically

Activity Overview

Students will use Sliders on the TI-Nspire to change coefficients of the basic sine and cosine function. Students will investigate how the graph changes by looking at different coefficients. Students will also investigate the sine and cosine graphs by comparing intersection points. Download the activity and worksheet that accompanies the activity for evaluation of learning.

Before the Activity

General knowledge of the basic trigonometric functions, sine and cosine is needed. Download the activity to the students handhelds before the activity.

During the Activity

During the activity, students can answer questions from the word document that accompanies this activity.
