Hii i am girl
y = xsin^-1 x/sqrt (1 - x^2)
let x= sin@
differentiating with respect to @
dX/d@ = cos@
cos@ = sqrt (1- x^2)
sec@= 1/sqrt(1 - x^2)
tan@ = x/sqrt(1- x^2)
@ = sin^-1x
y = sin@ @/cos@
y = tan@@
diffrenciating with respect to @
(dy/dx) cos@= sec^2@@ + tan@
dy/dx = secx (1/1- x^2 + (x/sqrt1-x^2)
(1 - x^2)dy/dx = (xsqrt(1 - x^2)+ 1)/sqrt(1 -x^2)
(1 - x^2)dy/dx =x +1/sqrt(1 - x^2)
