Smith’s Law states:
The area between two curves is the integral of the top curve minus the bottom curve.
I have emailed edexcel asking them to put this on their syllabus. If you think this is a vanity campaign, think of Boltzmann, after whom a constant is named – botzmann’s constant, k which is the raio of the universal gas constant N_A, Avagadro’s constant. There are billions of functions of useless constants whichcan be constructed as functions of other constants – more than enough for every person of the planet to have one named after them.
