(adsbygoogle = window.adsbygoogle || []).push({}); Phase shift and sinusoidal curve fitting - Finding.....

1. The problem statement, all variables and given/known data

"Find the period, amplitude, and phase shift of each function. Graph each function. Be sure to label key points"

y = 4sin(2x - pi)

2. Relevant equations

3. The attempt at a solution

So, I got...

Amplitude = 4

Period = 2pi/2 = 2

Phase shift: Would that be pheta/w ?, So pi/2 ?

Now here is where I get messed up.

I do not know how to get"Interval defining one cycle"and"Subinterval width"

How do I generate points from this?
