 Feb9 answered Is there a geometric interpretation of the product integral? Feb9 revised Integral $\int \ (2x+6)^5+\frac{10}{(3x-1)^2} \text{d}x$ added 3 characters in body; edited title Feb9 comment Nested radicals of 1000 square roots This would be close enough to the question with indefinitely many iterations, the possibility of a explicit answer is slim, should settle for the approximate one. Feb9 revised Sum $\sum_{n=2}^{\infty} \frac{n^4+3n^2+10n+10}{2^n(n^4+4)}$ edited title Feb9 revised Prove that the limit of $a_n = \frac{2n^3+n^2}{(n+2)^3}$ is $2$. edited title Feb8 revised Is $i = \sqrt{e^{\pi\sqrt{e^{\pi\sqrt\ldots}}}}$? edited title Feb8 revised If $\log_{12}54=a$ then $\log_{6}12=?$ added 4 characters in body; edited title Feb8 comment Parametric equation of degree 4 A little more explanation for mere mortals like me please. Feb8 revised Limit $\lim_{x\to\infty} \frac {(\ln(x))^k}x$ edited title Feb8 comment Limit $\lim_{x\to\infty} \frac {(\ln(x))^k}x$ Is that meant to be $(\ln x)^k$ or $\ln (x^k)$ ? Feb6 revised How to show that for $a_n := \left( \frac{(2n)!}{n!n^n} \right)$, $a_n \rightarrow 4/e$ [Edit removed during grace period] Feb5 revised Sum $\sum _{ n=1 }^{ \infty }{ \frac { 2n }{ \left( n+1 \right) ! } }$ edited title Feb2 revised Limit $\lim\limits_{n\to \infty} \sqrt [n]{\frac{(3n)!}{n!(2n+1)!}}$ deleted 22 characters in body; edited title Feb2 comment Why is $\int_0^1 \frac{dx}{\sqrt{1 - x^4}} = \frac{\sqrt{\pi}\,\Gamma(5/4)}{\Gamma(3/4)}$? math.stackexchange.com/questions/1122911/… Feb2 revised Singularities of ${1}/{\cos(\frac{1}{z})}$ edited title Feb2 comment Find the parametric equation of a circular helix in space with central axis the $z$-axis and radius $5$. Leave b as b, you don't need a specific value for it. Feb2 comment Singularities of ${1}/{\cos(\frac{1}{z})}$ @did : it collapses on IE windows RT to a single line, what are you using that does not collapse? Feb2 revised Singularities of ${1}/{\cos(\frac{1}{z})}$ edited title Feb2 comment Find the parametric equation of a circular helix in space with central axis the $z$-axis and radius $5$. I was mistaken that b can b found, b is a parameter on its own and can have any value. Feb2 comment Find the parametric equation of a circular helix in space with central axis the $z$-axis and radius $5$. No need to find the value of b, paramedic equation can have the b term in it.
