Question

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

Answer 1

Amplitude `=1`
Period `2pi`
Phase shift `=0`
Vertical shift `=-1`

`y=sintheta-1`
graph{sin x- 1 [-10, 10, -5, 5]}

Explanation:

`y=sin theta - 1`
Amplitude = 1, Period = `(2pi)/1=2pi`, Phase shift `=-(c/b)=0` & Vertical shift `=-1`
