 Aug20 revised proof of log-sum giving maximum value given equality constraint fix log and min Aug20 suggested approved edit on proof of log-sum giving maximum value given equality constraint Aug20 comment How to solve $\int \frac{\tan^{-1}x}{(1+x)^2}dx$? And please, leave only question here, without any other solved examples... Aug20 comment How to solve $\int \frac{\tan^{-1}x}{(1+x)^2}dx$? $\tan^{-1}(x)$ is an $\arctan(x)$, yes? Aug19 answered Evaluate $\int_2^4\frac{\sqrt{x^2-4}}{x^2}\mathrm dx$ Aug19 answered Is there any simple analytic method for solving $\sqrt{x}+y=7$ and $x+\sqrt{y}=11$ simultaneously.

Aug17 suggested rejected edit on Probability Distribution, where $E(X^2) = 2E(X)$ Aug17 revised Relation between $\dim V$ and $\dim V^{\star}$ improved math formatting Aug17 suggested approved edit on Relation between $\dim V$ and $\dim V^{\star}$ Aug17 answered How Matrix A is called $A^2=I$ Aug17 comment How Matrix A is called $A^2=I$ Involutory matrix. Aug17 comment How Matrix A is called $A^2=I$ Equal to identity matrix? I know about nilpotent, idempotent and periodic matrices. Aug17 comment Calculus of variations: big-O notation? Just replacement of terms smaller than $C^2$ with $O(C^2)$, assuming $C$ is small. Aug17 comment Calculus of variations: big-O notation? You have particular question on something or overall explanation? For last, some calculus textbook would be better. Aug17 comment May seem like a noob question: really, why can't we divide by 0? Maybe because it can be defined in many different ways and none of this definitions would be useful. Unlike $1+2+\cdots=-1/12$, where multiple definitions yields to the same result and have a practical results.
