Vedclass · Answer

(B) The given integral is of the form of the Beta function,$B(m, n) = \int_0^1 x^{m-1} (1-x)^{n-1} \, dx = \frac{\Gamma(m)\Gamma(n)}{\Gamma(m+n)}$.Here,$m-1 = 5/2 \implies m = 7/2$ and $n-1 = 3/2 \implies n = 5/2$.So,the integral is $B(7/2, 5/2) = \frac{\Gamma(7/2)\Gamma(5/2)}{\Gamma(7/2 + 5/2)} = \frac{\Gamma(7/2)\Gamma(5/2)}{\Gamma(6)}$.Using the property $\Gamma(n+1) = n\Gamma(n)$ and $\Gamma(1/2) = \sqrt{\pi}$:$\Gamma(7/2) = \frac{5}{2} \cdot \frac{3}{2} \cdot \frac{1}{2} \cdot \sqrt{\pi} = \frac{15\sqrt{\pi}}{8}$.$\Gamma(5/2) = \frac{3}{2} \cdot \frac{1}{2} \cdot \sqrt{\pi} = \frac{3\sqrt{\pi}}{4}$.$\Gamma(6) = 5! = 120$.Substituting these values:Integral $= \frac{(\frac{15\sqrt{\pi}}{8}) \cdot (\frac{3\sqrt{\pi}}{4})}{120} = \frac{45\pi}{32 \cdot 120} = \frac{45\pi}{3840} = \frac{3\pi}{256}$.
