Coefficients of a Sinusoid

Here is an applet that will let you explore the coefficients of a cosine curve. She how each of the variables changes the graph.
Now that you have explored the coefficients, you should be able to answer the following questions. 1. Which coefficient causes a vertical translation of the parent function? 2. Which coefficient causes a vertical dilation of the parent function? 3. Which coefficient causes a horizontal translation of the parent function? 4. Which coefficient causes a horizontal dilation of the parent function?
