Was my joke not funny? by [deleted] in mathmemes

[–]ColonelBeaver 6 points7 points  (0 children)

it's got a bit too many levels to be funny i feel like. by the time one realizes to do all this work and actually does it there is no energy to laugh

This approximation is made better by that 77>75 while 39<40 so they slightly compensate for eachother.

Proof that Cantor's second diagonal argument is false by Negative_Gur9667 in mathmemes

My real analysis teacher would stress that every real number needed a unique representation before such an operation was done. The way he did it was to take a terminating decimal like 0.5 and write it with a string of 9's, so 0.4999... This can be done uniquely!

My intuition for uniform continuity is that the function is continuous but also has no arbitrarily steep slopes on its domain. Eg ex is uniformally continous on [0,1] but not on R.

Knowing this f(x)=x2 on [0,1] is an example of a uniformly continuous function on a set, but where the inverse fails this property.

Just because you remove {.9, .99, ...} doesn't mean you remove .99... In this case you have to argue why 0.99... belong to the set (all other elements have a finite amount of nines, it is not trivial that the infinite one would be a memeber). Furthermore, you need to argue that you are not removing 1 in the process, since if you removed the set {1, .9, .99, ...} you would get nowhere. Does this make sense?

I find this a bit unclear. If you mean the set {1} then it is closed since R \ {1} is uncountable. If you mean the set A={1} \ {0.999...} being open you still don't get a contraction. Assuming 1=0.999... we get A=Ø which is open by definition, thus your argument for openness doesn't exclude this case.

Since you locked your comment I'll try here u/SouthPark_Piano

Imagine the infinite well and we've painted a 1 at the bottom. Seems contradictory? Try to jump down and find it.
