Removed the word "DEFINITE" and replaced it with "definite" Jan 22 suggested approved edit on Can every definite integral be expressed as a combination of elementary functions? Jan 22 revised Solving permutation problem Tried to make the formatting better Jan 22 suggested approved edit on Solving permutation problem Jan 22 comment How to use Hardy and Wright's text and what corresponding exercises/problem books can I do? That was certainly helpful.But I am open to more links/advice to choose from. Jan 22 revised How to use Hardy and Wright's text and what corresponding exercises/problem books can I do? Corrected typo Jan 22 asked How to use Hardy and Wright's text and what corresponding exercises/problem books can I do? Jan 21 accepted Limit of a function satisfying an inequality Jan 21 comment Limit of a function satisfying an inequality I didn't quite think of that(other conditions).Either way,thanks for your comments. Jan 21 comment Limit of a function satisfying an inequality To be honest, I have not yet completed a first course in rigorous calculus(I am currently doing Apostol' Calculus vol I and I haven't done much of it(only hundred odd pages).So I don't think I have the necessary background to read Kuzma's book(I can't see the preview of that page either).But still thank you.I don't even know what a measurable function is.So I really apologise for my ignorance. Jan 21 asked Limit of a function satisfying an inequality Jan 3 answered Proving $a^2+b^2=c^2$ where $a,b,c$ are side lengths of a right triangle. Jan 3 comment Proving $a^2+b^2=c^2$ where $a,b,c$ are side lengths of a right triangle. Well, the poster apparently has little experience with proofs(and probably geometry) and I doubt if the OP knows about the cosine rule. :) Jan 3 answered I haven't studied math in 12 years and need help wrapping my mind back around it Dec 30 comment Finding pairs of integers such that $x^2+3y$ and $y^2+3x$ are both perfect squares Oh.I just noticed.It was an edit by Shrivatsan.:D Dec 30 comment Finding pairs of integers such that $x^2+3y$ and $y^2+3x$ are both perfect squares How come this topic made it to the top of the list of asked questions?Does math.SE have some automatic system for bumping? Dec 30 comment Are there infinitely many primes of the form $6^{2n}+1$ or only finitely many? @ Pedro.Yes, I checked to find that as well.$6^{6}+1|6^{12}+1$
