EARTH CAN YOU HEAR ME NOW?
Trigonometric Functions, Graphs of Trigonometric Functions
Exploring space is a complex endeavor. Future destinations include Mars. Students will investigate, analyze and model the communication time lag between Earth and Mars. Transmitting a message between Earth and Mars could take up to 20 minutes because of the distance between the two planets.
Prerequisites: Students should have prior knowledge of plotting data on a coordinate plane, of solving equations, and of key characteristics of a sinusoidal function and the parent function, f(x)=sinx.
