## 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.

## What is the period of a sin function?

The period of a periodic function is the interval between two “matching” points on the graph. In other words, it’s the distance along the x-axis that the function has to travel before it starts to repeat its pattern. The basic sine and cosine functions have a period of 2π, while tangent has a period of π.
