An infinitely long string stretching along the x-axis, with a tension = 18.0N,
carries a transverse sinusoidal (harmonic) wave. The displacement, y(x,t),
perpendicular to the direction of travel, is:
y(x,1) = (0.350) sin( (0.0500 z)x+ (300.0 r)t). In this equation the units of both
y(x,1) and x are cm and t is in seconds.
