So, I have to self-teach myself part of my class. However, there's one part of my book I can't understad at all.

First, I would like to understand, why does a transverse motion has 3 variable, y,x, and t . In my book they give the explanation y=h(x,t) and when we find the formula of the wave we get y=Asin(kx +/- wt).

I'm wondering, if y is the displacement of one element of a string, then what does x represent? I'm all confused :/
