Differentiate `sin ^(-1) (1/sqrt(1+x^2))` with respect to 'x'

Text Solution

Verified by Experts

Let `y =sin ^(-1) (1/sqrt(1+x^2))` and ` x= cot Theta`
`y=sin ^(-1) ((1)/(sqrt(1+cot^2 theta)))=sin^(-1)(1/("cosec" theta))`
`therefore =sin^(1)(sin theta)=theta=cot^(-1)x`
`rArr dy/dx =d/dx cot^(-1)x=(-1)/(1+x^(2)).`
