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?
