  Ω= Σ_(n=1) ^∞ {n^2 (∫_0 ^( (π/2)) (( sin^( 2) (x ))/((sin(x)+cos(x))^( 4) )))^( n) dx}=?
$$ \\ $$$$\Omega=\:\underset{{n}=\mathrm{1}} {\overset{\infty} {\sum}}\left\{{n}^{\mathrm{2}} \left(\int_{\mathrm{0}} ^{\:\frac{\pi}{\mathrm{2}}} \frac{\:{sin}^{\:\mathrm{2}} \left({x}\:\right)}{\left({sin}\left({x}\right)+{cos}\left({x}\right)\right)^{\:\mathrm{4}} }\right)^{\:{n}} {dx}\right\}=? \\ $$$$ \\ $$
