What is the relationship between the keyword x and the expression x asin wt in the context of wave motion?

In the context of wave motion, the keyWord "x" represents the position of a point on the wave, while the expression "x asin wt" represents the displacement of that point at a given time "t". The relationship between the two is that the expression describes how the point at position "x" moves over time in a sinusoidal manner due to the wave motion.
