Question

pls. help me solve this.
find the derivatives
y=x/x^2-1
f(x)=x^2+1/x^2-1
pls show your solution.

Answer 1

the working is..

Answer 2

how is it done?

Answer 3

use the division rule of derivatives to get \[{(x^2-1)(1)-(x)(2x)}/(x^2-1)^2\]

Answer 4

for the first one.. the answer is -(x^2+1)/(x^2-1)^2

Answer 5

do you get it? or do u want me to explain more?

Answer 6

shessa???? do you know the formula?

Answer 7

\[v*du/dx- u*dv/dx/v^2\]

Answer 8

pls explain further.

Answer 9

right.. so i have applied the same formula to get the answer..:)

Answer 10

then you solve the bracket to get your answer.. you want me to do it too?

Answer 11

yup pls.

Answer 12

(v∗du/dx−u∗dv/dx)/v2 its this the whole under v^2..

Answer 13

oh ok you get in the numerator x^2-1-2x^2...

Answer 15

x^2-1(1)=X^2-1
then x(2x)=?
