The vertical displacement of an ocean wave is described by the function, y = A sin(ωt - kx). k is called the wave number (k = 2π/λ) and has a value of k = 19 rad/m. The remaining values are A = 4.5 m and ω = 15.5 rad/s.

Using y = A sin(B), input an expression for B where the wave would be traveling in the -x-direction.
