That looks really cool, thanks!

I began something like that some time ago.

Remembering I had some awful:
module MathExp
    class Function
         def self.sq(x = nil) Function.new(:sq, x, '2x', 'x^3/3') end

I was using String for functions, as I didn't know yet the power of coerce.
But that was quite easy to get derivative and integral.

Great job !
