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

Vedclass · Answer

(C) दिया गया है $f(x) = \int \frac{dx}{x^2+(\sqrt{2})^2}$.मानक समाकलन सूत्र $\int \frac{dx}{x^2+a^2} = \frac{1}{a} 	an^{-1}(\frac{x}{a}) + C$ का उपयोग करने पर:$f(x) = \frac{1}{\sqrt{2}} 	an^{-1}(\frac{x}{\sqrt{2}}) + C$.चूँकि $f(\sqrt{2}) = 0$ है,$x = \sqrt{2}$ प्रतिस्थापित करने पर:$0 = \frac{1}{\sqrt{2}} 	an^{-1}(\frac{\sqrt{2}}{\sqrt{2}}) + C$$0 = \frac{1}{\sqrt{2}} 	an^{-1}(1) + C$$0 = \frac{1}{\sqrt{2}} (\frac{\pi}{4}) + C$$C = -\frac{\pi}{4\sqrt{2}}$.अब,$f(0)$ ज्ञात करते हैं:$f(0) = \frac{1}{\sqrt{2}} 	an^{-1}(\frac{0}{\sqrt{2}}) - \frac{\pi}{4\sqrt{2}}$$f(0) = \frac{1}{\sqrt{2}} (0) - \frac{\pi}{4\sqrt{2}} = -\frac{\pi}{4\sqrt{2}}$.

यदि $f(x) = \int \frac{dx}{x^2+2}$ और $f(\sqrt{2}) = 0$ है,तो $f(0) =$
