Wave function proving problem

  1. Jan 13, 2008 #1
    1. The problem statement, all variables and given/known data

    Show that y(t-x/v) is a solution of the wave equation without taking any partial derivatives (hint: use your knowledge about f(x-vt)).

    2. Relevant equations


    3. The attempt at a solution

    what exactly is y(t-x/v) means, from dimension analysis, its the function of y(t). but how on earth this relate to y(x,t). rather confused of what this question is asking.

    kindly show me how to kick start this.thanks.
