Meta: Are questions about existence of a solution manual to a book allowed on MSE?

comment The position of a ladder leaning against a wall and touching a box under it
I am not sure whether the question should be closed as a duplicate. There is a difference between: "I've got this equation from a geometry problem, how do I solve it?" and "How do I solve this geometry problem?" But even if they should be considered duplicates, then the opposite direction would make much more sense in my opinion, since the newer question contains much more detail.

comment LCA - groups under continuous homomorphisms
Maybe you could mention where the problem comes from (in the other words, you could provide context).

comment Epsilon-Delta proof of $\lim_{x\to 2} x^2=4$
Some related older posts (maybe you will be able to find more of them): Prove that $\lim_{x\to 2}x^2=4$ using $\epsilon-\delta$ definition and Show that $f(x)=x^2$ is continuous at $a=2$ using the $\delta-\epsilon$ definition of continuity.

comment Epsilon-Delta proof of $\lim_{x\to 2} x^2=4$
I tried to edit your post using MathJax (TeX) for better readability. But I left the original version, too. If you are satisfied with the MathJax version, you could maybe remove the older ascii-version. Of course, if needed, edit the part I have added further, to get result you are satisfied with.
