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 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.
