WebThe Brocard or seven-point circle has diameterOK where K is the symmedian point, and the Brocard points are on this circle, and are mutual refections in the Brocard axis OK. It is well known that the Brocard angle manifests itself as ω = ∠KOΩ=∠KOΩ.

From definition we see that polar line is orthogonal to O P and it is relatively easy to prove that if A is on polar for B then B is on polar for A. Also, there is a theorem (which is harder to prove, but again not so hard, just use of the power of the point) which says ...

Brocard's problem is a problem in mathematics that seeks integer values of $${\displaystyle n}$$ such that $${\displaystyle n!+1}$$ is a perfect square, where $${\displaystyle n!}$$ is the factorial. Only three values of $${\displaystyle n}$$ are known — 4, 5, 7 — and it is not known whether there are any more. More … See more Pairs of the numbers $${\displaystyle (n,m)}$$ that solve Brocard's problem were named Brown numbers by Clifford A. Pickover in his 1995 book Keys to Infinity, after learning of the problem from Kevin S. Brown. As of … See more • Eric W.

WebAug 8, 2013 · One such problem was introduced by the French mathematician Henri Brocard in 1876 and later, in a separate paper, in 1885. Brocard inquired about a set of possible positive integers such that the equation is satisfied. The term in the equation is known as the factorial of . WebJan 27, 2024 · Usually a SERVFAIL is due to the server not handling DNSSEC correctly, but it doesn't look like either domain is DNSSEC-signed, so I don't think that's it. Perhaps someone who handles your DNS fixed something? But everything looks fine now, so I'm not sure what else to suggest. 2 Likes system closed February 26, 2024, 3:31pm #7 WebDec 13, 2024 · Brocard's problem is n! + 1 = m^2. The solutions to this problems are pairs of integers called Brown numbers (4,5), etc, of which only three are known.
