We launched rockets and measured how high they went using trig, but sometimes they just went too high to see.

If you’re reading this and you’re a mathematician you may not think this is very profound. This is just a little idea I had as I was thinking about the application of the unit circle before moving on with my students to graphing sine waves and other trig functions.

Say you’re on a Ferris Wheel at the county fair, and let’s superimpose the Ferris Wheel onto the unit circle. It’s easy to know when you’re all the way at the top of the Ferris Wheel () and when you’re all the way at the bottom (). Halfway is also pretty easy because it’s when you’re all the way to the sides( and ).

Pre-calulus students,

There will be a test on Trigonometry Wednesday, April 29th. We will review on Monday and Tuesday. It will cover general angles, radians, evaluating trig functions, and the unit circle.

UPDATE: The trig test has been rescheduled due to the number of snow days we’ve had this week. The test is currently scheduled for Thursday, Feb 26.

Test next week on right triangle trigonometry. It will cover…

- Setting up a trig ratio
- Special right triangles
- Solving for a missing side
- Solving for a missing angle

Get studying, good luck.

Here is an interesting thing I found on trig. I haven’t looked through it carefully yet. Let me know what you think.
