Any help is greatly appreciated, thanks! :)

We're presenting this HW orally on Monday, and I always get nervous in front of a crowd so I really want to make sure I'm understanding everything correctly and at least get most of this right. :) Thanks!

Answer 1

I'm not sure about all of yours, but I do know that on the first,  

Negation in English: The sequence {an}is neither monotone nor bounded, is not right because it could just be not monotone but still bounded (V, or, only requires one part to work).

Answer 2

Confer with your classmates. Don't be afraid. Relax. It's okay to be wrong. No one's perfect, and I'm sure your professor is understanding.

Answer 3

(b) and (d) have the wrong logical form.
