Mathematics Question from JEE Main 2023 · 6 April, Shift 1

Let y=y(x)y = y(x) be a solution of the differential equation (xcosx)dy+(xysinx+ycosx1)dx=0(x\cos x)\,dy + (xy\sin x + y\cos x - 1)\,dx = 0, 0<x<π20 < x < \frac{\pi}{2}. If π3y ⁣(π3)=3\frac{\pi}{3}\,y\!\left(\frac{\pi}{3}\right) = \sqrt{3}, then π6y ⁣(π6)+2y ⁣(π6)\left|\frac{\pi}{6}\,y''\!\left(\frac{\pi}{6}\right) + 2y'\!\left(\frac{\pi}{6}\right)\right| is equal to:
