Primitive of Reciprocal/Corollary 2
 It has been suggested that this page or section be merged into Derivative of Natural Logarithm Function. (Discuss) |
What would probably be best would be for this to be a corollary of the above page.
Until this has been finished, please leave {{refactor}} in the code.
New contributors: Refactoring is a task which is expected to be undertaken by experienced editors only. Because of the underlying complexity of the work needed, it is recommended that you do not embark on a refactoring task until you have become familiar with the structural nature of pages of $\mathsf{Pr} \infty \mathsf{fWiki}$.
