714- Modeling Noise-Cancelling Headphones with Trigonometric Functions

Saturday, April 18, 2015: 11:00 AM-12:00 PM
259 A (BCEC)


Lead Speaker:
Blake Whitley
Jennifer Nickell and Ashley Whitehead


Ever wondered how noise-cancelling headphones block out ambient noise in a room? This task was designed for students to reason about transformations and compositions of trig functions using GeoGebra to model sound waves. Videos and artifacts of student work and reasoning will be provided. Bring a laptop with GeoGebra or GSP to engage in the task!
