A sinusoidal wave with amplitude 4.60 cm, wavelength 15.2 cm, and frequency 3.38 Hz is observed to travel in the negative direction. (Use the following as necessary: x and t. Assume x is in meters and t is in seconds. Enter values to at least 4 decimal places. Do not enter units in your answers.)

(b) What is the wave function for this wave if y(x, t) = 4.60 cm at x = 5.00 cm and t = 0?
