Sol. ( quad y=left(sin ^{-1} xright)^{2} ) rentiaturg bofh sides ( int 1-x^{2} frac{d y}{d x}=2 sin ^{-1} x+x ) Díforentiating breth sides- ( sqrt{1-x^{2}} frac{d^{2} y}{d x^{2}}+frac{d y}{d x}left(frac{(-2 x)}{2 sqrt{1-x^{2}}}right)=frac{2}{sqrt{1-x^{2}}}+0 ) ( left(1-x^{2}right) frac{d^{2} y}{d x^{2}}+frac{d y}{d x}(-x)=2 ) 8 ( left(1-x^{2}right) frac{d^{2} y}{d x^{2}}-frac{x d y}{d x}-2=0 ) hemce proved: ( left[left(1-x^{2}right) frac{d^{2} y}{d x^{2}}-frac{x d y}{d x}=2right. )
