DifferentiableA draft page: Differentiable "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #2 20131129 14:09:55
Re: DifferentiableHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20131129 20:45:26
Re: DifferentiableSome corrections.
More precisely, they are not differentiable only at integer values of x. (If x is not an integer they are perfectly differentiable at x.)

Re: Differentiable
I certainly would, JFF could not have said it better. f(x) is differentiable at 0 according to the SE. x^2 sin( 1/ x ) would not be because it is not defined at 0.
