Description of the parts of a periodic functon

1. Characteristics of the Sinusoidal Function Median Line Median Line is sometimes called the axis, and is the horizontal line midway between the maximum and minimum value of the sine curve. Maximum value Minimum value

2. Amplitude amplitude The Amplitude (a) is the maximum displacement of the curve from the median. a = max value – min value 2

3. Period period The Period is the length of the shortest interval in which the wave repeats itself.
