Radio Station KTNS

Activity Overview

This lesson involves determining the distance one can hear a radio station as a function of the range of the station.

Objectives

  • Students will solve a problem experimentally by fitting a function to a set of data.
  • Students will solve the same problem theoretically by making and verifying conjectures using algebraic and trigonometric methods.

Vocabulary

  • Law of Sines
  • Law of Cosines

About the Lesson

This lesson involves determining the distance one can hear a radio station as a function of the range of the station.
As a result, students will:

  • Solve the problem empirically by fitting a regression equation to a set of gathered data.
  • Solve the problem theoretically by finding an equation involving the Law of Cosines and the Law of Sines.
