comment Non-standard numbers and exponential form of Zeta function
I mean counting the red dots. You know. Counting things. Then plugging n=10 in the n(n+1)/2 formula and check if it's the same as you seem to claim.

comment Non-standard numbers and exponential form of Zeta function
You should actually count the number of red dots in the 6th pictures and compare with what your formula says.

comment Non-standard numbers and exponential form of Zeta function
I don't see how the standard part of $4\tau^2$ is $-4/3$ instead of $0$. Did you choose this value just so the standard part of $\omega_-^2$ is $-1/12$ ? I also don't see the relationship between $\Bbb N^2$ and $1+2+3+\ldots$ and even less so between $\Bbb N^3$ and $\zeta(-2)$

comment Why does the diophantine equation $x^2+x+1=7^y$ have no integer solutions?
"However, this is a relatively easy task for y>3, so we are done" care to give some details ?

answered If a statement is true for every element in a sequence, would it be true at limit when $n \to \infty$?

it vanishes for some other branch of arctan.

comment Identifying This Curve Algorithm?
it's the degree 3 polynomial interpolation sending (0,1/3,2/3,1) to (a,b,c,d)

comment What is the smallest subfield of the complex numbers which has the property that every polynomial of odd degree has a root
why do you think there should be a "smallest" such field ? The intersection of two fields having that property doesn't necessarily have that property

comment What hyperbolic space *really* looks like
I wouldn't want to live in hyperbolic space. As you walk, the stuff you see in the horizon moves quickly to get behind you as new hyperbolic lands unfold in front of you. Wait no. You wouldn't be able to see very far away (a candle gets dimmer exponentially as you walk away from it) and if you get drunk for 5 minutes you could be lost forever...

comment When a vector space will be a complete lattice?
are the finite dimensional cone-induced lattices all isomorphic to $P = \Bbb R^{+n} \subset E = \Bbb R^n$ ?

comment Conventions adopted for extended reals
if we define $\infty-\infty = 5$, and substract the both parts of $\infty+1 = \infty$ by $\infty$, we get $5=5$, no contradiction.

comment Conventions adopted for extended reals
because $0 \times 17 = 0$, so whatever value we give to $0/0$ we come to a contradiction $1 = 17$...

comment Conventions adopted for extended reals
how is that any different from $0/0$ or $\infty/\infty$ ??

comment Conventions adopted for extended reals
why can't those last two be "conveniently defined" ?

comment Is it possible to solve sudoku without backtracking?
It is possible if you have a giant dictionnary with 10^81 entries telling you for each grid if there is a unique completion and if so, what it is.

how is $3\Bbb Z/9 \Bbb Z$ isomorphic to $\Bbb Z_3$ ?? (as a ring)
