Question

Differentiate;
x^2/(1+x)^2

Answer 1

This is of the form u/v.
(u/v)'=(u'v-v'u)/v^2
Here u=x^2 and v=(1+x)^2.
(x^n)'=nx^(n-1)
Can u do it @emcrazy14?

Answer 2

I got the answer -2x/(1+x)^3. Is it correct?

Answer 3

differentiate: 1/(1/x + 1)^2

Answer 4

check the sign @emcrazy14.
It shud be 2x/(1+x)^3

Answer 5

Ok, thanks. Do I multiply (x+1) with a negative sign to change it into (1+x) so that it cancels with the the denominator (1+x)^4?

Answer 6

just ask the wolf for differentiation Question.

Answer 7

nope.
(x+1)=(1+x)

Answer 8

Then how oes it become +2x? :O

Answer 9

@experimentX : wolf? :O
*does
