Sine Functions



In the following examples, follow these steps:

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

General Form for Sine Curves

A = Amplitude; think of this as the y-dilation of the curve
B = Frequency; think of this as the x-dilation of the curve. This important value helps you find the period of the sine curve:

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

D = Translation in the y-axis
