Ok so what I want to know is, is this valid? If so what does it mean?
Like mathman said, use Δx. dx has its own meaning. Δx can represent some small distance along the x-axis.cubic said:It has to be along a distance dx.
cubic said:dx is the width of each strip. dx would then be the width of the first strip. Δx is the width of a finite number of strips, which is not what I am looking for.
