1. Section 4.2.3 Frequency of Sine and Cosine Graphs

2. Lesson Objective: Students will: Practice stretching a sine and cosine graph horizontally. Learn about angular frequency and its relationship to period.

3. Angular Frequency How frequently a cycle of a function occurs between 0 and 2π is the angular frequency. The letter b is used to represent angular frequency.

4. General Equation for Sine a = amplitude b = angular frequency h = horizontal shift k = vertical shift

5. Period The product of the period, p, and the angular frequency, b, is 2π.

10. Closure Given, explain all the transformations for the function.
