I just totally had a mental lapse here... What's the derivative of TanSquaredX?

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?

Is it 2(Times)sec2x? no. the chain rule says $\displaystyle \frac d{dx}f(g(x)) = f'(g(x)) \cdot g'(x)$ you're missing something
