Hello again, I was just wondering that since the rules of Cantor's cardinal numbers in set theory do not apply to the infinity obtained by limits in calculus (ex. x->0, y=1/x=infinity), does that mean that this infinity is the largest quantity in both calculus and mathematics? |
No, it means that it is not a cardinal number.
If you are this interested in this topic, you had better start at the beginning with a good set theory textbook and work your way through it, doing all the exercises. (Or take a course in the subject; that would probably be more fun if the other students are keen.) You clearly want to know about this in more depth than we can provide in a few emails.
Good Hunting!
