SUMMARY
The wave function that describes a wave moving in the -x direction is given by y(x,t) = Asin(-kx - wt). The other two functions, y(x,t) = Asin(kx + wt) and y(x,t) = Acos(kx + wt), represent waves moving in the +x direction. The phase relationship indicates that the sine function with a negative argument corresponds to motion in the negative x-direction, while the cosine function can be transformed into a sine function with a phase shift of π/2, which also indicates positive direction movement.
