Solutions to the Wave Equation

In one dimension there are at least three distinct solutions to the wave equation that we are interested in. Two of these solutions propagate along the string - energy is transported from one place to another by the wave. The third is a stationary solution, in the sense that the wave doesn't propagate in one direction or the other (not in the sense that the string doesn't move). But first:
