(There are a half-dozen other ways in which the formatting of that table is terrible; I have also replaced hyphens with minus signs for the table entries, but one could do much more.) --[[User:JayBeeEll|JBL]] ([[User_talk:JayBeeEll|talk]]) 13:32, 29 May 2021 (UTC)
 
== Arithmetic derivative ==
 
The notion of arithmetic (logarithmic) derivative is an old and well-known notion in number theory. See for instance (1) E. J. Barbeau, Remarks on an arithmetic derivative, Canad. Math. Bull. 4(2), 117–122 (1961); (2)V. Ufnarovski, B. Åhlander, How to differentiate a number, J. Integer Seq. 6, Article 03.3.4 (2003); (3)P. Haukkanen, J. K. Merikoski, T. Tossavainen, On arithmetic partial differential equations, J. Integer Seq. 19, Article 16.8.6 (2016). --[[User:Sapphorain|Sapphorain]] ([[User talk:Sapphorain|talk]]) 21:08, 18 May 2022 (UTC)
