# How do you find the amplitude and period of y= 6 sin x?

The amplitude is $6$ the period $2 \pi$.
$\sin \left(x\right)$ oscillate between $- 1$ and $+ 1$ because it is constructed in the circle of radius $1$. Then, when it is multiplied by $6$ it will oscillate between $- 6$ and $+ 6$, so the amplitude will be $6$.
The period is when the function repeats its values. For the $\sin$ this happens after $2 \pi$. The variable $x$ is in the $\sin$ without any modification, so the period is still $2 \pi$.
