# How do you graph y=1/4sinpix?

sine has an initial amplitude of 1 so its range is [-1 to 1] but in your function the amplitude is reduced by a factor of $\frac{1}{4}$ so it will be a sine wave ranging from $- \frac{1}{4}$ to $\frac{1}{4}$
Now the period, normally the period would be $2 \pi$, but in your case we're adjusting the period input by $\pi$ so the graph would have a period of 2.
