# How do you find the amplitude and period of y=1/4sin2pix?

May 20, 2018

Amplitude = $\frac{1}{4}$
Period (T) = $1$

#### Explanation:

$y = \frac{1}{4} \sin 2 \pi x$ is in the general form $y = a \sin b x$
Where:
a = amplitude
b = used to find period (T)

Therefore,
amplitude = $\frac{1}{4}$
period (T) = $\frac{2 \pi}{n} = \frac{2 \pi}{2 \pi} = 1$
