Vedclass · Answer

(B) આપણે જાણીએ છીએ કે $\operatorname{Tan}^{-1}(a) - \operatorname{Tan}^{-1}(b) = \operatorname{Tan}^{-1}\left(\frac{a-b}{1+ab}\right)$.આપણે પદોને આ રીતે ફરીથી લખી શકીએ:$\operatorname{Tan}^{-1}\left(\frac{x}{1+2x^2}\right) = \operatorname{Tan}^{-1}\left(\frac{2x-x}{1+(2x)(x)}\right) = \operatorname{Tan}^{-1}(2x) - \operatorname{Tan}^{-1}(x)$.$\operatorname{Tan}^{-1}\left(\frac{x}{1+6x^2}\right) = \operatorname{Tan}^{-1}\left(\frac{3x-2x}{1+(3x)(2x)}\right) = \operatorname{Tan}^{-1}(3x) - \operatorname{Tan}^{-1}(2x)$.આ કિંમતોને $y$ ના સમીકરણમાં મૂકતા:$y = (\operatorname{Tan}^{-1}(2x) - \operatorname{Tan}^{-1}(x)) + (\operatorname{Tan}^{-1}(3x) - \operatorname{Tan}^{-1}(2x)) = \operatorname{Tan}^{-1}(3x) - \operatorname{Tan}^{-1}(x)$.$x$ ની સાપેક્ષમાં વિકલન કરતા:$\frac{dy}{dx} = \frac{d}{dx}(\operatorname{Tan}^{-1}(3x)) - \frac{d}{dx}(\operatorname{Tan}^{-1}(x)) = \frac{3}{1+(3x)^2} - \frac{1}{1+x^2} = \frac{3}{9x^2+1} - \frac{1}{x^2+1}$.

$y = \operatorname{Tan}^{-1}\left(\frac{x}{1+2x^2}\right) + \operatorname{Tan}^{-1}\left(\frac{x}{1+6x^2}\right)$ હોય,તો $\frac{dy}{dx} = $
