Published on November 26, 2011

Objectives

  • Students will determine the type of function modeled by the height of a capsule on the London Eye observation wheel.
  • Students will translate observational information to use as the parameters of a cosine function.
  • Students will determine the amplitude, frequency, period, and midline of a cosine function when given information in verbal or graphical form.

Vocabulary

  • amplitude
  • frequency
  • midline
  • parameters of a function
  • period
  • periodic function
  • sinusoidal function

About the Lesson

This lesson involves creating an appropriate equation to model the height of a capsule on the wheel.
As a result, students will:

  • Use a slider to animate the function modeled by the height of a capsule on the London Eye observation wheel.
  • Discover the concepts of amplitude, frequency, period, and midline.
  • Determine the amplitude, frequency, period, and midline of the "observation wheel" function.
