## How do you find the period of a function?

The period is the distance between each repeating wave of the function, so from tip to tip of the function’s graph.

As you can see from this graph, the distance between the tips of the function is 3.034 – 1.463 = 1.57.

1.57 is the same as pi over 2, which is the same as we got from using the formula.

## How do you find the period of a graph?

If we have a sine function of the form f(x) = Asin(Bx + C) + D, then the period of the function is 2π / |B|. Therefore, to find the period of the function f(x) = Asin(Bx + C) + D, we follow these steps: Identify B in the function f(x) = Asin(Bx + C) + D.

## What is period of a function?

The distance between the repetition of any function is called the period of the function. For a trigonometric function, the length of one complete cycle is called a period. For any trigonometry graph function, we can take x = 0 as the starting point.
