1. 6.3 Graphing Sine and Cosine Functions Objective: Use the graphs of the sine and cosine functions.

2. If the values of a function are the same for each given interval of the domain, the function is said to periodic. Consider the graphs of y = sin x and y = cos x shown here. Notice that for both graphs the period is 2π and the range is from -1 to 1, inclusive. y = sin x y = cos x

3. Properties of the Graph of y = sin x

4. Properties of the Graph of y = cos x

6. Find the values of Θ for which cos = 0 is true.

7. Graph y = sin x for 6π ≤ x ≤ 8π.

8. Graph y = cos x for -6π ≤ x ≤ -4π.
