Please help me learn math

Answer 1

the period of this graph is
`\pi`

Explanation:

The period is the length of the section that repeats. So for this graph, we need to calculate the distance between 2 peaks or 2 troughs of the curve.

Let's look at the peaks (maximums).

One is at x = 0 and the next is at x =
`\pi`

`\pi` - 0 =
`\pi`

Therefore, the period of this graph is
`\pi`
