Exploring Sinusoidal Functions

Activity Overview

In this activity, students will approximate the zeros, minima, maxima, and period of sinusoidal functions by using the Transformation Graphing app.

About the Lesson

In this activity, students systematically explore the effect of the coefficients on the graphs of sinusoidal functions. Terminology describing the graph—amplitude, period, frequency, phase shift, midline, and vertical offset—is introduced, then reinforced as the student calculates these values directly from the graph using the graphing calculator and sliders.

*Note: This activity contains an optional AP Practice Questions document for those students preparing for the AP Precalculus Exam.
