In the following examples, follow these steps:

- Draw the XY-axis with your EZ Graphing slide case.
- Graph the parent function.
- Now add to your graph Reflection, Dilation and Translation in this order.
- Finally, click on the problem to check the solution.

# General Form for Cosine Curves

A = Amplitude; in a way, this is the y-dilation of the curve

B = Frequency; in a way, this is the x-dilation of the curve. This important value helps you find the period of the cosine curve:

C = Translation in the x-axis; also known as the phase shift

D = Translation in the y-axis
