First Apotome of Medial is Irrational
Theorem
In the words of Euclid:
If from a medial straight line there be subtracted a medial straight line commensurable with the whole in square only, and which contains with the whole a rational rectangle, the remainder is irrational. And let it be called a first apotome of a m... | {} |
# Speeding up parentheses (and lots more) in R
August 19, 2010

(This article was first published on Radford Neal's blog » R Programming, and kindly contributed to R-bloggers)
As I noted here, enclosing sub-expressions in parentheses is slower in R than enclosing them in curly brackets. I now know why, and I’ve mo... | {} |

### Caching sagetex results
Is there a way to cache computations already done in a latex file using sagetex so that, for example, if I add a Sage code line in foo.tex when I run sage foo.sagetex.sage the computation starts from that line and not from the beginning?
The best thing would be t... | {} |

This problem is a harder version of TRENDGCD.
Given $n$ and $m$, compute
$$S(n, m) = \sum_{i=1}^n \sum_{j=1}^m ij \cdot f(\gcd(i,j)),$$
where $f(n) = (\mu(n))^2 n$ and $\mu(n)$ is the Möbius function, that is, $f(n) = n$ if $n$ is square-free and $0$ otherwise. Especially, $f... | {} |
