 Apr 29 comment What is the best study plan for the AMC 12/AIME/USAMO competitions? I actually had the privilege of reading the book Count Down and got motivated by it.I guess it is indeed about work ethic. Apr 28 accepted Proving continuity of $f$ Apr 28 comment Proving continuity of $f$ Why can we assume that $x_0=0$ and $f(x_0)=0$?I have had little or no exposure to convergent sequences.I'd probably revisit this after I gain enough background to appreciate this. Apr 28 asked Proving continuity of $f$ Apr 5 comment solution to $7^{a}+1 =3^{b}+5^{c}$ for natural $a$,$b$ and $c$ Can you please provide a link?

Apr 2 asked How to show $\int_{0}^{\frac{\pi}{2}} \cos^m x\sin^m x dx=2^{-m}\int_{0}^{\frac{\pi}{2}} \cos^m x dx$? Feb 29 accepted How to prove that $\frac{\cos\alpha}{\cos\beta}=a/b$ Feb 29 comment Looking for a Calculus Textbook Actually, here in Kolkata,high school begins from the sixth grade. Feb 29 asked How to prove that $\frac{\cos\alpha}{\cos\beta}=a/b$ Feb 29 comment Looking for a Calculus Textbook The author is in the "third grade of high school", i.e. the OP is probably in the 8 th or 9 th grade of school.I am currently studying calculus from Apostol and I really like his gentle and yet rigorous style. Jan 29 comment Inequality regarding exponents(similar to Bernoulli's inequality) I have edited the question.
