Find and simplify the following derivatives:

thanks :D - Oct 23rd 2008, 03:41 PMskeeter
all of these are derivatives involving the use the chain rule ... let's see how you do at least one of them.

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 - Oct 23rd 2008, 04:04 PMskeeter

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

so the cos one would be

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

... and you said you didn't know how.
