# How do you find the amplitude, period, vertical and phase shift and graph y=sintheta-1?

Oct 8, 2017

Amplitude $= 1$
Period $2 \pi$
Phase shift $= 0$
Vertical shift $= - 1$

$y = \sin \theta - 1$
graph{sin x- 1 [-10, 10, -5, 5]}

#### Explanation:

$y = \sin \theta - 1$
Amplitude = 1, Period = $\frac{2 \pi}{1} = 2 \pi$, Phase shift $= - \left(\frac{c}{b}\right) = 0$ & Vertical shift $= - 1$
