You can ask Siri on an iPhone “What planes are flying over me?” and she will tell you exactly that. But exactly how far out of a radius does Siri report planes? This activity will help you and your students use trigonometry and angles of elevation and depression find out! Applications include the
understand the relationship of the secant, cosecant and cotangent
functions to cosine, sine and tangent, and use properties and graphs of all six trigonometric functions for angles of any magnitude;
• use trigonometrical identities for the simplification and exact
evaluation of expressions and in th
This is a two day exploration of the connections between sine waves and music. It ties in various iPad apps to help students see how all music is composed of sine waves. I have also created a smore flyer to go along with the lesson: https://www.smore.com/gy9h4
XYFlyer is a simple puzzle app that provides a series of challenges around constructing equations. With each equation constructed you can immediately see the resulting graph and how different changes to each equation affect the graph.
We've created over 200 levels that get more and more challenging
This video is to help students in math and science classes learn the Greek alphabet. The pronunciation is the English way of saying the letters in an American accent. It is NOT meant for those actually trying to learn Greek as a foreign language.

Guided instructions to create an animated unit circle on Geometer's Sketchpad. Students will create the unit circle and the reference triangle. They will animate a point on the circle to see what happens as the arc length increases.
Can be used to create trigonometric functions on GSP.
