Hello, Super Mallow!

What's the derivative of: .$\displaystyle f(x) \:=\:\tan^2\!x$ ?

Think of it as: .$\displaystyle f(x) \;=\;[\tan x]^2$ .and use the Chain Rule.

Yup, I know that. This is actually really simple for me, but for some reason, I'm having a mental lapse on trig functions to a power right now!

Is it 2(Times)sec2x? - Nov 26th 2007, 07:12 PMJhevon
