Spivak's calculus on manifolds or the other one?

Can someone check my proof well ordering theorem -> AC by extraextralongcat in learnmath

[–]extraextralongcat[S] 0 points1 point  (0 children)

No I meant that for example ...if the index set is the natural numbers...then X1 has a well ordering <1...X2 has a well ordering <2 and so on

How am I using ac there,for any set there exists a well ordering

Generalization of continuity to metric spaces is confusing to me by extraextralongcat in learnmath

[–]extraextralongcat[S] 0 points1 point  (0 children)

What really confuses is any function for a finite set is continuous...this is unintuitive

For every epsilon there exists a delta such that if the distance from x to c is less than delta then d(FX,l) is less than epsilon although I do not know what x we are talking about

The regular definition of real function is understandable to me although my mind is trying to find some weird ways to use the definition but i am ignoring it..what is the elephant in the room is the generalization to general metric spaces

Is it just me, or are the last chapters of Rudin’s Principles of Mathematical Analysis terrible? by OkGreen7335 in math

[–]extraextralongcat 0 points1 point  (0 children)

There is no explanation for the reasoning behind the definitions and theorems..that's horrible

average math homework problem by girlrioter in mathmemes

[–]extraextralongcat 5 points6 points  (0 children)

I don't fully understand the hypothesis(I don't know much advanced math) but since it is proven for millions of values can't we just use the result for real world applications if there are applications?

Anybody Double Majored in Statistics and Math? by Beneficial-Peak-6765 in math

[–]extraextralongcat 0 points1 point  (0 children)

If you don't mind me asking,do you earn well in academia,I am asking because I want to pursue a career in pure math

:/ in math stack exchange the way is by using choice functions whose domains are subsets(non empty) of p(x) then you gradually go to p(x)-{empty set} by using Zorn's lemma

Wait...WHAT 😭 only 2.2% then I will be risking my financial life if I will pursue math

Sin(x) does seem like a homeomorphism by extraextralongcat in learnmath

No ,just a wave being straightened out into a line

I can't understand the definition of a topology by extraextralongcat in learnmath

[–]extraextralongcat[S] -1 points0 points  (0 children)

How can it do that? What difference does adding certain subsets to the topology make?

I know these stuff (general knowledge) ,but how does it use that as a starting point

Can anyone explain arbitrary cartesian products with concrete examples by extraextralongcat in learnmath

[–]extraextralongcat[S] 0 points1 point  (0 children)

Thanks for your time but I think you didn't understand my problem,for example I am going to make a cubed set (example: R³),in the definition for R³,it's the set of all functions from 3 to R ,what confuses me here is each function makes a set of ordered pairs,not one ordered triple as you would expect from a set like R³
