_{Vector surface integral. Delta x is the change in x, with no preference as to the size of that change. So you could pick any two x-values, say x_1=3 and x_2=50. Delta x is then the difference between the two, so 47. dx however is the distance between two x-values when they get infinitely close to eachother, so if x_1 = 3 and x_2 = 3+h, then dx = h, if the limit of h is ... }
