$\sin \left(2 x^{2}\right) \log _{e}\left(\tan x^{2}\right) d y+\left(4 x y-4 \sqrt{2} x \sin \left(x^{2}-\frac{\pi}{4}\right)\right) d x=0$,$0 < x < \sqrt{\frac{\pi}{2}}$ નો ઉકેલ વક્ર $y=y(x)$ છે. જે બિંદુ $\left(\sqrt{\frac{\pi}{6}}, 1\right)$ માંથી પસાર થાય છે. તો $\left|y\left(\sqrt{\frac{\pi}{3}}\right)\right|=$ ..............
