Changes in Period and Amplitude of the Sine Function

Curated and Reviewed by Lesson Planet

How does a change in amplitude or period affect the equation of a sine function? Scholars move sliders to change the frequency and period of the sine function. The interactive displays the resulting equation, and pupils determine the effect on the period of the function based upon the frequency and amplitude.
