General solutions for cos(1/x)
This may seem a bit too simple of a question:
Do we write solutions to cos(1/x) = 0 as:
1/x = PI/2 (+/-) n(PI) where n is an integer or
1/x = n(PI) (+/-) PI/2 where n is an integer?

Rakudo, the leading Perl6 implementation, is not perfect, and performance is a particularly sore subject. However, the pioneer does not ask ‘Is it fast?’, but rather ‘Is it fast enough?’, or perhaps

XYZ-Wing, sudokuwiki.org
In this example the candidate number is 1 and F9 is the Hinge. It can see a 1/2 in D9 and a 1/4 in F1. We can reason this way: If D9 contains a 2 then F1 and F9 become a naked pair of 1/4 - and the
naked pair rule applies. Same with F1.

Bohr's semiclassical aproach
What makes the Bohr model "semi"-classical is that he required that the angular momentum of the electron be quantized (integer multiples of [itex]\hbar[/itex]).
