## Find the Equation of a Sinusoidal Function from a Graph

A function that has the same general shape as a sine or cosine function is known as a sinusoidal function. The general forms of sinusoidal functions are y= Asin(Bx−C)+D y = A sin ( B x − C) + D and y = Acos(Bx−C)+D y = A cos ( B x − C)

## Sinusoidal

Equation of a sinusoidal curve Given the graph of a sinusoidal function, we can write its equation in the form y = A·sin (B (x - C)) + D using the following steps. D: To find D, take the average of a local maximum and minimum of the sinusoid.
