- What is infinity divided by infinity? - Mathematics Stack Exchange
I know that $\\infty \\infty$ is not generally defined However, if we have 2 equal infinities divided by each other, would it be 1? if we have an infinity divided by another half-as-big infinity, for

Why is the infinite sphere contractible? I know a proof from Hatcher p 88, but I don't understand how this is possible I really understand the statement and the proof, but in my imagination this
- How can Cyclic groups be infinite - Mathematics Stack Exchange
I am a little confused about how a cyclic group can be infinite To provide an example, look at $\\langle 1\\rangle$ under the binary operation of addition You can never make any negative numbers with
- What is the difference between infinite and transfinite?
Infinite simply means "not finite", both in the colloquial sense and in the technical sense (where we first define the term "finite") There is no technical definition that I am aware of for "transfinite" Nevertheless, I can attest to my personal use Transfinite is good when there is a notion of order, so "transfinite ordinal", or when you want to talk about non-standard real numbers which
- Does infinite equal infinite? - Mathematics Stack Exchange
All three integrals are divergent and infinite and have the regularized value zero, but two of them are equal but not equal to the third one In other cases of divergent integrals or series, the regularized value and or growth rate (germ at infinity) or behavior at a singularity can differ as well or the differences can compensate for each
