Vedclass · Answer

(B) ધારો કે $I = \int_{-\frac{\pi}{8092}}^{\frac{\pi}{8092}} \frac{\sec (2023 x)}{1+(2023)^{(2023 x)}} d x$. ગુણધર્મ $\int_{-a}^{a} f(x) d x = \int_{0}^{a} [f(x) + f(-x)] d x$ નો ઉપયોગ કરતા: $f(x) = \frac{\sec (2023 x)}{1+(2023)^{(2023 x)}}$ $f(-x) = \frac{\sec (-2023 x)}{1+(2023)^{(-2023 x)}} = \frac{\sec (2023 x)}{1+\frac{1}{(2023)^{(2023 x)}}} = \frac{(2023)^{(2023 x)} \sec (2023 x)}{(2023)^{(2023 x)}+1}$ $f(x)$ અને $f(-x)$ નો સરવાળો કરતા: $f(x) + f(-x) = \frac{\sec (2023 x) [1 + (2023)^{(2023 x)}]}{1+(2023)^{(2023 x)}} = \sec (2023 x)$ તેથી, $I = \int_{0}^{\frac{\pi}{8092}} \sec (2023 x) d x$ $= \left[ \frac{1}{2023} \log |\sec (2023 x) + 	an (2023 x)| ight]_{0}^{\frac{\pi}{8092}}$ $= \frac{1}{2023} [\log |\sec(\frac{\pi}{4}) + 	an(\frac{\pi}{4})| - \log |\sec(0) + 	an(0)|]$ $= \frac{1}{2023} [\log (\sqrt{2} + 1) - \log (1 + 0)]$ $= \frac{\log (\sqrt{2} + 1)}{2023}$

$\int_{-\frac{\pi}{8092}}^{\frac{\pi}{8092}} \frac{\sec (2023 x)}{1+(2023)^{(2023 x)}} d x=$
