QLD (Nspire): Pendulum Swing – Part 1
by Texas Instruments

Published on June 14, 2016

Objectives

Identify contexts suitable for modelling by trigonometric functions and use them to solve practical problems.

Vocabulary

Period, amplitude, translation, dilation, parameter

About the Lesson

Students use a CBR motion detector to measure the motion of a basic pendulum. Practical measurements and numerical data support the identification of the parameters in trigonometric function used to model the data. The phenomenal accuracy of the data and associated function encourages students to fine-tune their parameters to improve their model, constantly rehearsing the associated transformations supported with visual feedback and practical alignment making this a truly memorable mathematics activity.
