When you look at the calculus, the interest rate of corrosion R in equation 2 is developed given that the derivative dN/dt, in which dN signifies the tiny amount of atoms that rot in an infinitesimally short period of time period dt. Exchanging R by the comparable dN/dt results in the differential formula
