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)
