They say if you don't open your mouth you can't say something stupid, but, they say that.
Heh, got your goat, there, eh, Hancher. Huff and puff, you. Quit with your ad hominem attacks.
You ignoramus, I just noted Dirac's delta is notarealfunction. Or, that's _not_ really the case. And Heaviside's step is continuous, now. For that matter it's a real function.
http://mathworld.wolfram.com/RealFunction.html
You're slippin'. I think you mean Heaviside's step isn't a C^\infty or smooth function, it's not even C^1. Though of course there was a time when step wasn't "modernly" a function: when all functions were C^\infty: hundreds of years ago. You're slippin', backward, and quit dragging us with you.
Then, no, I've never claimed that EF(1) has a standard value as Eudoxus/Cauchy/Dedekind, an element of the complete ordered field can be halved, again and again ad infinitum. However, it is the properties of the function and its range that are relevant, in the standard, and to the standard. So, the construction is modeled with real functions, and obviously all the elements of the range are in the reals, and they go from zero to one. Of course, I went further than that and describe the real numbers as at once complete ordered field and partially ordered ring with rather restricted transfer principle.
And, m > n implies EF(m) > EF(n), because here m > n. It is true, that. The functions there modeling it are all constant monotone increasing, and they all go to one.
Do you or do you not have that lim Sum 1/2^n = 2? Because as above you would have just proved that false, were you not wrong.
Quit trying to segregate me you bastard, that's a typical fallacious argument which we're all quite familiar with from you. And don't change the discussion subject to simple derogation. This is about "Cantor's first proof in DETAILS" not your latest slander. And, it's about Finlayson's proofs in detail, who is me.
Yeah, I do have a new theory that includes the standard: I have "A Theory", that includes the standard. Bring your A game. Yeah I already discovered a new system: same as the old system, and then some.
I don't expect you're familiar with Riemann, Lobachevsky, Connes, etc geometry or the meromorphological (I'm not very well either), in plain old pure mathematics and their applications, though of course some erudite readers are. They're in letters. (Here, Physics Letters.) Then, for nilpotent infinitesimals, Leibniz invented methods of the integral calculus, and we still use today the "d" for differential and integral S for summation, of raw differentials, cited in _every_ calculus text as the mode and universal notation. Of course, our rigorous development of the fundamental theorems of calculus, Cauchy/ Weierstrass, and etcetera, keep people from going overboard, but moreso develop and maintain the general curriculum for application. Leibniz' notation survives, and it speaks most directly to our mathematical intuition.
The standard naturals and reals are insufficient for all that EF entails, while it's quite perfectly modeled in them: standardly. And, Goedel proves there is more to the standard than the standard. Of course, it would be fallacious to claim that because Goedel proves there are true statements about the elements of discourse extra the standard that these are thus true: instead, it is defined: constructively. Goedel accommodates that.
