ધારો કે $f:[-1, 2] \rightarrow [0, \infty)$ એક સતત વિધેય છે જેથી તમામ $x \in [-1, 2]$ માટે $f(x) = f(1-x)$ થાય. ધારો કે $R_1 = \int_{-1}^2 x f(x) dx$ અને $R_2$ એ $y = f(x)$,$x = -1$,$x = 2$ અને $x$-અક્ષ દ્વારા ઘેરાયેલા પ્રદેશનું ક્ષેત્રફળ છે. તો

જો $f(5-x)=f(x)$ અને $\int_2^3 f(x) dx=2$ હોય,તો $\int_2^3 x f(x) dx=$

વિધાન $(A)$: $\int_{\frac{\pi}{6}}^{\frac{\pi}{3}} \frac{(\sin x)^{\sqrt{2}} dx}{(\sin x)^{\sqrt{2}}+(\cos x)^{\sqrt{2}}} = \frac{\pi}{12}$
કારણ $(R)$: $\int_{a}^{b} \frac{f(x) dx}{f(x)+f(a+b-x)} = \frac{b-a}{2}$

$\int_{\log \frac{1}{2}}^{\log 2} \sin \left(\frac{e^{x}-1}{e^{x}+1}\right) dx=$
