Infinitesimals

What do you mean dy and dx aren't a term in an expression? You dummy anon, just use the Levi-Civita field! You just have to express every real number as a power series over the rationals involving the infinitesimal d and then you can recover the same notion of derivative Leibniz used. Also, it properly formalizes the Dirac delta function.
