1. Describe how you would create sketches of the following sinusoidal functions: o y = 2 sin (x + 180) o y = 1/2 COS 3(X - 180) + 2 o y = -2 cos (1/4X + 90) 2. Create one equation for cos(0) and one equation for sin(0) for the following graph: 200 300 500 -2- 3. Create descriptions of the changes in the appearance of sinusoidal graphs for each of the factors in the transformation form of a trigonometric function (y = a sin k(8 - c) + d ). For example, describe how changes in "a" change the appearance of the graph. Go to Settings to activate Windows 4. What transformation do you need to apply to change a sin function to a cos function
