sech
[edit]what is sech in the converging formula for the Madelung constant of NaCl ? — Preceding unsigned comment added by 37.138.169.178 (talk) 13:57, 25 October 2019 (UTC)
- Sech(x) is the hyperbolic secant of x. 2804:14D:4683:10CD:9184:E581:DE56:E4E (talk) 14:43, 27 November 2023 (UTC)
any example how to use it?
Comparison of fluorite with CsCl & sphalerite
[edit]The fluorite Madeling constant, as seen from the fluoride ions, is not intermediate between sphalerite and CsCl, but equal to the latter due to the identical simple cubic arrangement of said fluoride ions. Olthe3rd1 (talk) 13:56, 1 October 2024 (UTC)
