I am enrolled in a introductory course for higher mathematics (modern analysis/algebra) so it should be pretty straightforward for anyone with math chops. I just dont have the time to do it myself this week as I am overwhelmed with exams in my other classes. Mostly its just set theory on the latest one, not too long either only 6 problems. I cant imagine it taking longer than 30-40 minutes for someone who knows what their doing.
I'm offering 0.08 btc with another 0.05 bonus if it comes back with a perfect score.

Can you give an example for the problems? I maybe able to do it.

This is from the last homework assignment.. the more recent one I think is involving infinite sets more.. I should have the latest one in a few hours, but right now I'm simply looking to see if this gets any attention.

Let f : X = Z × {0} → Y = Z × {1} be the map f(n, 0) = (2n + 1, 1) and g : Y =
Z × {1} → X = Z × {0} the map g(n, 1) = (2n − 2, 0).
(i) Which elements of X have exactly one predecessor? (i.e. x ∈ im g but g
−1
(x) ∈/ im f).
Which elements of X are the endpoints of chains of length 2 but not of longer chains?
Which of Xe, Xo and Xi does (0, 0) belong to ?
(ii) Which set does the element (2nk, 0) belong to, where k is odd and n ≥ 0?

Speak of the devil.. the latest one was just posted and in fact it is actually 7 problems, but they appear shorter than expected so I'm keeping the payout unless someone feels otherwise.
Here is a sample from that one:

Construct an explicit bijection f; [0, 1] → (0, 1], where [0, 1] is the closed interval in
R and (0, 1] is half open

Scarred you all off huh?
...No takers seriously? The class aint that advanced

If anyone could recommend another place for me to find this service fulfilled it would be greatly appreciated :)
preferably with btc but not a requirement

Escrowing prize may help you to find people.

IMHO it is better if you make a contest everytime, escrow the prize. You will get better answers and more people will participate.
