Problem

A sinusoidal wave travels in the

+x

direction on a stretched string with amplitude

0.030\,\text{m}

, frequency

6.0\,\text{Hz}

, and wavelength

1.2\,\text{m}

. At

x=0

and

t=0

, the string segment is at a crest. Write the explicit equation

y(x,t)

that describes the displacement of the string.
