A sinusoidal wave on a string is described by the equation y = (0.191 m) sin (0.745 x - 42.9 t), where x and y are in meters and t is in seconds. If the linear mass density of the string is 11.7 g/m ...

a) ... determine the phase constant.

b) ... the phase of the wave at x = 2.29 cm and t = 0.197 s.
