From Wikipedia, the free encyclopedia

[edit] Use in elementary calculus

Should this not be mentioned? Every calculus text I've ever read (e.g. Stewart's) teaches students logarithmic differentiation as a method to take derivatives of complicated products (since this converts them into sums, which one can differentiate term by term). I don't have time right now to do this, but does anyone else think there could be more here (along the lines of chain rule or implicit function#Implicit differentiation? --Cheeser1 10:41, 17 October 2007 (UTC)
