Q1

Let y = y(x) satisfies the equation \(\frac{\mathrm{dy}}{\mathrm{dx}}-|\mathrm{A}|=0\), for all x > 0, where \(\mathrm{A}=\left[\begin{matrix}\mathrm{y} & \mathrm{sinx} & 1 \\ 0 & -1 & 1 \\ 2 & 0 & \frac{1}{\mathrm{x}}\end{matrix}\right]\). If y(π) = π + 2, then the value of \(\mathrm{y}\left(\frac{\pi }{2}\right)\) is:
