Question

HELP DIFFERENTIATE :
Below

Answer 1

\[\frac{ 1 }{ 1-x ^{2} }\]

Answer 2

Give it your best shot and I'll help you when you mess up.

Answer 3

well i though the ones cancel each other out to = -x^2 and that becomes 2x

Answer 4

but im pretty sure thats not right

Answer 5

That sounds right to me so far, I'm not sure though because I haven't seen your answer.

Answer 6

what do you mean answer?

Answer 7

What are you getting for the derivative?

Answer 8

2x

Answer 9

kainui is such a smart girl who fflutters calculus

Answer 10

Still not resolved?

Answer 11

is that the answer

Answer 12

What is the answer? Where?

Answer 13

\[\frac{ 1 }{ 1-x^2 }\]
can also be expressed as:
\[(1-x^2)^{-1}\]
using chain rule to differentiate you'll have:
\[-1(1-x^2)^{-2} (-2x)dx\]
\[2x (1-x^2)^{-2}dx\]
\[\frac{ 2x }{ (1-x^2)^{2} } dx\]
