    If \[y=c{{e}^{{{\sin }^{-1}}x}}\], then corresponding to this the differential equation is

    A)                 \[\frac{dy}{dx}=\frac{y}{\sqrt{1-{{x}^{2}}}}\]           

    B)                 \[\frac{dy}{dx}=\frac{1}{\sqrt{1-{{x}^{2}}}}\]\[\]

    C)                 \[\frac{dy}{dx}=\frac{x}{\sqrt{1-{{x}^{2}}}}\]           

    D)                 None of these

    Correct Answer: A

    Solution :

                       \[y=c{{e}^{{{\sin }^{-1}}x}}\]. Differentiate it w.r.t. x, we get                                 \[\frac{dy}{dx}=c{{e}^{{{\sin }^{-1}}x}}.\frac{1}{\sqrt{1-{{x}^{2}}}}=\frac{y}{\sqrt{1-{{x}^{2}}}}\] or \[\frac{dy}{dx}=\frac{y}{\sqrt{1-{{x}^{2}}}}\].
