Exploring Periodic Data

The period of a function is 

• how long one cycle is before the function repeats
• how high and low the function goes from the center line
• the range of the function

Amplitude refers to....

• how high and low the function varies from the center line.
• the length of the function
• how often the function repeats

Midline refers to....

• how high and low the function varies from the center line.
• the length of the function
• how often the function repeats
• horizontal line half way between max and min of function
