The integrating factor of differential euation `(1-x^(2))(dy)/(dx)-xy=1 " is"`

A

`-x`

B

`(x)/(1x^(2))`

C

`sqrt(1-x^(2))`

D

`(1)/(2)log(1-x^(2))`

Text Solution

Verified by Experts

The correct Answer is:
C

We have,
`(1-x^(2))(dy)/(dx)=xy-1rArr(dy)/(dx)-((x)/(1-x^(2)))y=(1)/(1-x^(2))`
It is a linear differential equation with I.F. given by
`"I.F. "=e^(-int(x)/(1-x^(2))dx)=e^((1)/(2)log(1-x^(2)))=sqrt(1-x^(2))`
