Differentiate 2/((1-x^2)^2)
What I'm having trouble with is when you move (1-x^2)^2 to the numerator is it all negative?
I need help on the first step only, i think i can do the rest.

use the exponents property :

$\large \frac{1}{a^{n}} = a^{-n}$

$ \dfrac{2}{(1-x^2)^2}$

ganeshie8 · Answer

$\large   \frac{2}{(1-x^2)^2} = 2(1-x^2)^{-2}$

anonymous · Answer

Ohhhh so only the power again...

ganeshie8 · Answer

yup !

anonymous · Answer

I keep getting that mixed up for some reason.

anonymous · Answer

quotient rule is just alot of movement going on and can easily be viewed as the simpler to work product rule

anonymous · Answer

We haven't learnt the quotient rule yet, and for this question the chain rule is needed.

anonymous · Answer

the chain rule is always needed regardless of the rule :)  it just that in most
cases an x' = dx/dx = 1 pops out
