comment Why does implicit differentiation work on non-functions?
+1 for keeping it simple and accessible.

comment Searching for analytical or topological proof(s) of the Cayley-Hamilton theorem
I think I remember seeing a proof in which the CHT was shown to hold for a dense set of matrices, and then extended by continuity. I think the dense set in question was the set of complex-diagonalizable matrices.

comment Explanation of Cauchy's root test / criterion
There are no similarities between Cauchy's criterion and his root test, other than that they're both named after Cauchy.

comment An algorithmic approach to constructing the real numbers
@AsafKaragila If somebody proved that the numbers produced by my (sketched) construction are exactly the computable reals, I would certainly accept that answer.

comment Which hot math research fields became insignificant later on?
Quaternions in the nineteenth century, and traditional algebra in the sense of the concrete computation of roots of polynomials.

comment Find the group of automorphisms of the Petersen graph
Standard drawings of the Petersen graph are highly symmetric. Use your visual intuition to list all the automorphisms (and then use your logical mind to make sure that's all of them).

comment How to prove if log is rational/irrational
Could you pin down a more specific question? "Advice on approaching thought construct to logs" is very broad and vague.

comment Create dynamic cities of perspective angle x
Why does a 75° angle limit how deep your buildings can be?

comment A Different Type of Knights and Knaves
This is exactly the same as the standard Knight/Knave puzzle involving two doors. The proposition "the left door is the correct one" is replaced by "someone has proven GC", that's all.

comment Hashing With Chaining Collision
Could you be a little more detailed about how the hashing works? The objects are numbers $1...1000$, the keys are numbers $0...9$, but what does "two keys map two elements to one index" mean?

comment Shortest path between two points via two disks
Do you really mean a point in the disk, or in the circle?

comment Finding a cubic polynomial whose splitting field over $\mathbb{Q}$ equals $\mathbb{Q}(a)$ if $a$ is any of its roots
What about $x^3-1$? Its splitting field is generated by a single root, but that doesn't quite fit your question because you have to be careful which root you choose.

comment Why is $0/0$ not $\Bbb R$?
What would it help to say it's equal to $\mathbb R$? What problems would be easier to solve or have more elegant solutions? What theorems would be simplified?

comment Which book is appropriate for a Chemistry student that needs to learn basics about integrals?
I think the wording "non-mathematical student" suggests something like an art or history student, so I took the liberty of editing your title.

comment Why is $\sin \theta$ just $\theta$ for a small $\theta$?
What's going on with all these downvotes?

comment What is the relationship between dim(Im(T)) and dim(Im(T^2))
@Dansmith If by "from $V$ to $V$" you mean a surjective map from $V$ to $V$, then you're correct.

comment Directly prove that $2x^2 -4x + 3 > 0$ for all real $x$
You're not that new to proofs. There's no "hard line" between proofs and the exercices you've done all your mathematical life, the question "solve $5x+2=3$" is asking for a proof that a particular number solves that equation.

comment Why are multiples of abundant numbers also abundant numbers?
You don't want a "less formal" proof, you want a more detailed proof.
