Question

(B) खंडशः समाकलन का उपयोग करते हुए: $\int u \, dv = uv - \int v \, du$. मान लीजिए $u = 	an^{-1} x$ और $dv = x \, dx$. तब $du = \frac{1}{1+x^2} \, dx$

Vedclass · Accepted Answer

$\frac{\pi}{4} - \frac{1}{2}$

(B) खंडशः समाकलन का उपयोग करते हुए: $\int u \, dv = uv - \int v \, du$. मान लीजिए $u = 	an^{-1} x$ और $dv = x \, dx$. तब $du = \frac{1}{1+x^2} \, dx$ और $v = \frac{x^2}{2}$.$\int_0^1 x 	an^{-1} x \, dx = \left[ \frac{x^2}{2} 	an^{-1} x ight]_0^1 - \int_0^1 \frac{x^2}{2(1+x^2)} \, dx$$= \left( \frac{1}{2} \cdot \frac{\pi}{4} - 0 ight) - \frac{1}{2} \int_0^1 \frac{x^2+1-1}{1+x^2} \, dx$$= \frac{\pi}{8} - \frac{1}{2} \int_0^1 \left( 1 - \frac{1}{1+x^2} ight) \, dx$$= \frac{\pi}{8} - \frac{1}{2} \left[ x - 	an^{-1} x ight]_0^1$$= \frac{\pi}{8} - \frac{1}{2} \left( (1 - \frac{\pi}{4}) - (0 - 0) ight)$$= \frac{\pi}{8} - \frac{1}{2} + \frac{\pi}{8} = \frac{\pi}{4} - \frac{1}{2}$.
