comment Partitioning the Non-Negative Integers Into 3 Sets
I want to make sure you haven't mistyped, because two answers have now been posted which do not answer the question you asked. Both would be correct if 8 were not in A, 11 or 14 were not in B, or 10 and 13 were not in C. Saying as that constitutes a significant portion of the numbers, I would encourage people to not be so quick in assuming what the problem is asking.

Would you be all right with using Liouville's Theorem in the proof?

Measure Theory by Pal Halmos is quite good, in my opinion.

comment Contrapositive Epsilon-Delta Limits?
I'm not really sure what you are looking for in terms of validation, maybe what you need to do is rewrite your argument in terms of natural language, in stead of logical symbolism. Everything you wrote is correct, and your conclusion is sound, but it is possible that all of the superfluous notation is confusing you.

comment Can universal instantiation be used more than once?
This may not be particularly interesting to say, but it is indeed that case that, for all real numbers $a$ there exists a real number $c$ such that, for all positive numbers $e$, $e>a+c$.

comment Does every inner product space has an orthogonal basis?
Try by starting with a basis, and from that construct, one-by-one, a basis you can demonstrate to be orthogonal.

comment How many non-ordered quadruples satisfy $a+b+c+d=18$?
Your question is equivalent to this one :math.stackexchange.com/questions/169213/… for the case of N=18 and K=4.

comment Is there any function that never gives an answer other than 0/0 when applying L'Hôpital's rule?
I provided the answer before the clarification. Others have now given better examples.

comment Adjustable Sigmoid Curve (S-Curve) from (0,0) to (1,1)
I'm not sure if it has the analytic properties that you want, but the CDF of a beta distribution is pretty versatile and meets your explicit requirements.
