M5L3 Amplitude By M Willatt Graphs made on desmos.com
Amplitude •
Is the distance from the midline of the sine or cosine curve to the top or bottom
•
Because it is a distance, it cannot be negative
•
To find amplitude given an equation, take the absolute value of your leading coefficient
•
To find amplitude from a graph, find the difference in height from the bottom of the curve (minimum) to the top of the curve (maximum), and divide it by 2.
Amplitude - Is the distance from the midline of the

Amplitude - To find amplitude from a graph, find the
difference in height from the bottom of the curve (minimum) to the top of the curve (maximum), and divide it by 2. Below the distance is 6 so a=3.

Period •
How long a function takes to complete a cycle.
•
Or, how long it takes to repeat itself.
•
To find period from the sine or cosine equation, you look at the coefficient in front of the angle (x or θ). Period = (2π)/coefficient of angle
•
To find period from a graph, pick a height (such as a peak) and see how long it takes to return to that height.
Period - How long a function take to complete a cycle, or how long it takes to repeat itself. Below pd=2pi.
