 Nov15 comment Newbie question about the re-application of a function on its result I believe this is a dupe. Unfortunately I am not able to find the previous one. Nov15 comment Proving an identity involving terms in arithmetic progression. @Deb: I was talking about "Prove an Identity" or whatever you had before. Nov15 comment Proving an identity involving terms in arithmetic progression. @Debanjan: If you don't want to mug it, I suggest you try it first. At least edit the question with the ideas you had. Nov15 comment Proving an identity involving terms in arithmetic progression. @Debanjan: What have you tried so far? Nov15 comment Proving an identity involving terms in arithmetic progression. @Chandru: Yes. a_i are in arithmetic progression, I believe. Nov15 answered What is the length of a continued fraction expansion of a rational number? Nov15 comment Solving $2x - \sin 2x = \pi/2$ for $0 < x < \pi/2$ Not sure what you mean. All I am saying is that it can be written in terms of well known constants. I guess we are just agreeing :-) Nov15 revised Solving $2x - \sin 2x = \pi/2$ for $0 < x < \pi/2$ added 117 characters in body; added 12 characters in body Nov15 comment Solving $2x - \sin 2x = \pi/2$ for $0 < x < \pi/2$ If you assume the Dottie number to be part of the "closed form" constants, then there is a closed form solution. See my answer.

This answer does not help in that regard (the reason for my -1). The mistakes are irrelevant. Nov15 comment $G$ finite abelian. $G/H$, $G/K$ primary cyclic. $H\cap K=1$. $H\neq 1\neq K$. Is $HK=G$? +1 for showing the attempt. Nov15 revised Polynomials, derivatives and repeated roots added 93 characters in body
