To begin with, if you are not able to define what it means for a function f(x) to be differentiable
at some point x=a, one of the many things that are illformed is your calculoose. Respectively
it will have a definition missing, you always start with "for a smooth function f(x) bla bla..."
but you nowhere define it rigorously. So I guess new calculoose is incompletely defined,
lets take this as a form of illformedness. How do you define your smooth without limit?
