Given a position vs time graph of simple harmonic motion of an object and using the equation
x(t) = xo = A sin (ωt +Φ), how am I supposed to find Φ?
I can easily find A and the period (T).
I also know T = 2 pi / ω, so I can find ω.
But I don't know x(t) and t. I tried finding random points in the graph and plugging them into the rearranged equation:
sin-1(x(t)- xo / (A)) - ωt = Φ
but I'm getting numbers that change depending on x(t) and t.
So how am I supposed to get Φ and should it not be constant?
