Square root of 3

 * – ( View AfD View log | edits since nomination)

As noted in WT:AFD, having multiple articles for individual square roots is "more than enough". SQRT(2) is special, if for no other reason that it's the first one. The others, not so much. I'll be nominating Square root of 3, Square root of 5, Square root of 6, and Square root of 7. The same argument applies to them all, but I'll make them distinct AfDs because bundled AfDs so often become train wrecks. -- RoySmith (talk) 00:25, 17 June 2022 (UTC)

 * Keep. Central in geometry in the measurement of equilateral triangles, hexagons, and cubes, and (unlike $$\sqrt5$$ and the golden ratio) with no closely-related number to redirect to. Because of its connection to triangles and cubes, frequently used in refinement of spatial subdivisions. Apparently this number even has significant applications in relativistic physics . Meets GNG: multiple publications have this number as their main topic . We definitely shouldn't have more than a handful of articles on these individual square roots, but I think this one is independently notable. —David Eppstein (talk) 00:50, 17 June 2022 (UTC)
 * Keep per David Eppstein. Also see previous root 5 deletion discussion from long ago Articles for deletion/Square root of 5. Note that unbundled AfDs may also become train wrecks. Dicklyon (talk) 03:26, 17 June 2022 (UTC)
 * Keep per David's points. The number has clear importance and significant coverage. — Ceso femmuin mbolgaig mbung, mellohi! (投稿) 04:20, 17 June 2022 (UTC)
 * Keep. Definitely notable, per Notability (numbers): (1) plenty of sources exist – anything in rudimentary geometry and trigonometry – in addition to special interest in several fields of physics (e.g., power engineering and statistical mechanics), (2) OEIS decimal expansion at and continued fraction at, (3) the article references The Penguin Dictionary of Curious and Interesting Numbers, (4) also known as Theodorus' constant. With this, GNG is satisfied as well. ComplexRational (talk) 13:58, 17 June 2022 (UTC)
 * Keep per others above. There is clearly a substantial literature concerning special properties of this number. I do not understand the basis for suggesting deletion. Newyorkbrad (talk) 15:41, 17 June 2022 (UTC)
 * Keep per others above as well. I’m not so versed, but I’d imagine that numerical concepts that have been around for centuries and millennia and studied for as long are bound to have enough intensive studies that them being declared not notable would be an arduous and monumental task.

 * Strong keep per everything stated. Trigonometric values involving the square root of three are essential. Historically, it has been a number that has interested mathematicians deeply. It's also part of the essential geometries of the triangle and hexagon. It's an article that can definitely be positively expanded, instead of removed. Thank you.

 * Keep because of its importance in trigonometry, and for other reasons. Check for snow in Antarctica or for the viability of snowballs in Riyadh.  Robert McClenon (talk) 17:02, 22 June 2022 (UTC)
 * Keep The 30-60-90 triangle is perhaps the second most famous following the 45-45-90, and is known for a side length of 1 opposite the 30, square root of 3 opposite the 60, and 2 opposite the 90. This helps for some of the core values of trigonometry, like tangent of 30° and 60°, sine of 60° and cosine of 30°. This square root is very important and notable, and should be kept. 68.198.188.106 (talk) 22:24, 23 June 2022 (UTC)
