Talk:Differentiation of trigonometric functions

From Wikipedia, the free encyclopedia

[edit] Inverses

There should probably also be the inverse trig functions because I can't find another page that has proofs for them. --Bobianite (talk) 01:32, 17 April 2008 (UTC)

Just wondering, since all the proofs for inverse trig functions are almost identical (as I am finding out while I do them), does anyone have a good way to put all of them into one single generalized proof? I tried creating a generalized explanation, but what about a proof? --Bobianite (talk) 01:53, 27 April 2008 (UTC)

[edit] Other things

I think the "a" needs to be included, as in the derivative of cos(ax) is -asin(ax)... right? Well yeah, the "a"s need to be included, to help people like me (Bonzai273 (talk) 16:22, 25 May 2008 (UTC))
