Exploring Period...Period.

Activity Description

Activity Guide

In this activity, periodic graphs and the period of the sine function are investigated.

Mathematical Topics:  the meaning of period, periodic graphs, the graph of y = sin(x), the graph of y = sin(bx), scaling, domain, and frequency.

Mathematical Thinking:  Analyze graphs, make predictions and conjectures about the effects of the variable b in the equation y = asin[b(x-c)]+d, and derive periodic formulas.

Technology: Students will use the interactive website activity at ExploreMath located at:

Below is a sample screen shot of the ExploreMath activity.
