A wave pulse is travelling on a string at 2 m/s. displacement y of the particle at x = 0 at any time t is given by
`y=2/(t^2+1)`
Find
(i) Expression of the function y = (x, t) i.e., displacement of a particle position x and time t.

Explanation

by replacing t by `(t - (x)/(v))` , we can get the desired wave function i.e.
`y = (2)/((t - (x)/92)^(2)+1)`
