Functions exist that are integrable but nowhere differentiable.
Consider a lacunary series, for example.

Yet more nonsense. The question, for example:
For given x, is x^2 < a is most definitely a decision problem that
is in NP.

This claim is so totally ridiculous as to defy understanding.

Once again, I suggest you consider f(x) = x. It is most definitely
continuous and most definitely has a finite representation.

This sentence is just total gibberish. Exactly what is a
'polynomial in infinity'?????

More nonsense. Any input that you supply to any computer function
is most definitely finite in its representation. A different
representation
might be infinite in length, but the representation actually used, in
whatever
alphabet you choose is most definitely finite.

And I keep responding that your posts are nonsense.
And I give concrete examples of why they are nonsense.
But you don't seem to get the message.

In brief: You have ALMOST ZERO understanding of the topics you are
trying to discuss, and you garble the little that you do understand.
