Exploring transformations of y=cos(x) (in radians)

1. Start by moving slider a. What happens to the equation and what happens to the curve? [br](for positive and negative numbers?)[br]2. Put slider a back to a=1. Move slider b. What happens to the equation and what happens to the curve? (for positive and negative numbers)[br]3. Put slider b back to b=1. Move slider c. What happens to the equation and what happens to the curve? (for positive and negative numbers)[br]4. Put slider c back to c=0. Move slider d. What happens to the equation and what happens to the curve? (for positive and negative numbers)[br]5. Experiment and observe what happens when you combine 2 or more transformations.
