Talk:Techniques for differentiation

From Wikipedia, the free encyclopedia

Lethe: As to your change of (\sec x)^2 to \sec^2 x, I think that should be reverted, as it could easily be thought to mean the sec(sec(x)). I've always been annoyed by people using that notation as in Trigonometry#Proofs for common formulas. This notation is far to similar to that in function composition.He Who Is 20:50, 4 June 2006 (UTC)

The notation is unfortunate for the reason you cite. But that notation is standard, whereas your notation is not. -lethe ^{talk +} 21:06, 4 June 2006 (UTC)

I have to say that in my experience, I have seen both notations used equally often. But in the case of trigonometric functions I have rarely seen the composite function notation, so I suppose it's alright.He Who Is 21:17, 4 June 2006 (UTC)

[edit] duplication

Now that I see the article, I'm not sure what the intended goal was, but it doesn't seem to contain anything that isn't already in Table of derivatives. That article is for an exhaustive list of derivatives of trig/hyperbolic trig functions etc. So what is this article for? -lethe ^{talk +} 20:34, 4 June 2006 (UTC)

Well, perhaps some proofs of these could be added, if they aren't show anywhere else already. Bobianite 18:59, 14 October 2007 (UTC)

Okay, now I'm starting to see this article the same way Lethe does. Much of the article is just a duplication, and even the proofs that I added could be found elsewhere. Techniques for integration sounds like a better article as integration requires tricks and tips. But differentiation? There isn't much technique or skill involved as far as I can see in this page, unless an expert can come along and adds some. --Bobianite (talk) 17:30, 6 April 2008 (UTC)
