i know they are the chain rule which is

but I dont know how to do these chain rules with cos, sec and tan to exponents of more then 1 - October 23rd 2008, 04:04 PMskeeter

do the cosine one. - October 23rd 2008, 04:19 PMiz1hp

- October 23rd 2008, 04:34 PMiz1hp
so the cos one would be

- October 23rd 2008, 04:45 PMiz1hp
so the tan one is...
