Homework Statement
A sinusoidal wave traveling in the –x direction (to the left) has an amplitude of 20.0 cm, a wavelength of 35.0 cm and a frequency of 12.0 Hz. The transverse position of an element of the medium at t = 0, x = 0 is y = –3.00 cm and the element has a positive velocity here. (a) Sketch the wave at t = 0. (b) Find the angular wave number, period, angular frequency and wave speed of the wave. (c) Write an expression for the wave function y(x,t).

The Attempt at a Solution
[/B]
I solved for the phase constant by subbing in the initial values and found -0.151 rad. however, the solution said that there are other possible phase constants, such as π + 0.151 rad and 2π - 0.151rad, etc. I was wondering if someone could explain how to find the other phase constant values.
Thanks
