Let α\alphaα and β\betaβ be real numbers such that −π4<β<0<α<π4-\frac{\pi}{4}\lt \beta\lt 0\lt \alpha\lt \frac{\pi}{4}−4π​<β<0<α<4π​. If sin⁡(α+β)=13\sin (\alpha+\beta)=\frac{1}{3}sin(α+β)=31​ and cos⁡(α−β)=23\cos (\alpha-\beta)=\frac{2}{3}cos(α−β)=32​, then the greatest integer less than or equal to (sin⁡αcos⁡β+cos⁡βsin⁡α+cos⁡αsin⁡β+sin⁡βcos⁡α)2\left(\frac{\sin \alpha}{\cos \beta}+\frac{\cos \beta}{\sin \alpha}+\frac{\cos \alpha}{\sin \beta}+\frac{\sin \beta}{\cos \alpha}\right)^{2}(cosβsinα​+sinαcosβ​+sinβcosα​+cosαsinβ​)2 is
