Question

consider a non- periodic wave that is described by y(x) = 12/(3+x^2) at t = 0 s.(a) what is the function that describes it at any arbitrary time t given that it moves in the negative x direction at a speed. (b) sketch the pulse at time t = 0, t = 1s, t =2s, if it moves in the positive x direction at 3m/s

Answer 1

This is tricky because if you want to describe the function at any time , I would think that it would be y(t), but it only moves in the -x direction when time is negative! So I'm not really sure what to do here.
