Supremums and Infimums (Introduction to Real Analysis I)

[pzzldstudent]

This is the only way I knew how to get all the math symbols in one document. I hope the link works.

I've done all my work there on the document.

Any help, corrections, tips, suggestions are greatly appreciated. Thank you very much!

Most look good - think about whether 0 \in \mathbb{N}.

As a comment: for some of the sequences you have comments like this: ''the sup is 1 when n is odd''

That isn't the correct way to think about it. The range of the sequence is a set of numbers, and you are looking for the supremum of that set. If that is indeed 1, you don't need to make any reference to the value of n - simply say \sup \mathcal{C} = 1
