Problem

If at

t = 0

, a travelling wave pulse on a string is described by the function,

y = \frac{10}{(x^2 + 2)}

Here,

x

and

y

are in metre and

t

in second. What will be the wave function representing the pulse at time

t

, if the pulse is propagating along positive

x

-axis with speed 2 m/s?
