Which of the following represents a standing wave? A)y = (6.0 mm)sin[(3.0 m^-1)x + (2.0 s^-1)t] - (6.0 mm)cos[(3.0 m^-1)x + 2.0] B)y = (6.0 mm)cos[(3.0 m^-1)x - (2.0 s^-1)t] + (6.0 mm)cos[(2.0 s^-1)t + (3.0 m^-1)x] C)y = (6.0 mm)cos[(3.0 m^-1)x - (2.0 s^-1)t] - (6.0 mm)sin[(2.0 s^-1)t - 3.0] D)y = (6.0 mm)sin[(3.0 m^-1)x - (2.0 s^-1)t] - (6.0 mm)cos[(2.0 s^-1)t + (3.0 m^-1)x] E)y = (6.0 mm)sin[(3.0 m^-1)x] + (6.0 mm)cos[(2.0 s^-1)t]
