Trigonometric Functions
|
Students measure the height of a fixed point on a hula hoop as it makes a complete revolution. Rather than using Sine = Opposite/Hypotenuse, we talk about sine being the vertical height in a unit circle.
This is a resource I got from an EMATHS Algebra 2 conference. |

I took this problem from Emaths. The numbers in the original problem were meant to be easier but it caused confusion with my students who were in track. I've revised the problem to include lengths on standard high school and NCAA tracks. This is a great 2 or 3 day task: circles, trig, dimensional analysis, volume, composite shapes. I love it! Here's the link.
