(B) ધારો કે $f = 	an ^{-1}\left(\frac{\sqrt{1+x^{2}}-1}{x}ight)$.$x = 	an 	heta$ લેતા,$	heta = 	an ^{-1} x$.તેથી $f = 	an ^{-1}\left(\frac{\sec 	heta - 1}{	an 	heta}ight) = 	an ^{-1}\left(\frac{1 - \cos 	heta}{\sin 	heta}ight) = 	an ^{-1}\left(	an \frac{	heta}{2}ight) = \frac{	heta}{2} = \frac{1}{2} 	an ^{-1} x$.આમ,$\frac{df}{dx} = \frac{1}{2(1+x^{2})}$.ધારો કે $g = 	an ^{-1}\left(\frac{2x\sqrt{1-x^{2}}}{1-2x^{2}}ight)$.$x = \sin 	heta$ લેતા,$	heta = \sin ^{-1} x$.તેથી $g = 	an ^{-1}\left(\frac{2 \sin 	heta \cos 	heta}{1-2 \sin ^{2} 	heta}ight) = 	an ^{-1}(	an 2	heta) = 2	heta = 2 \sin ^{-1} x$.આમ,$\frac{dg}{dx} = \frac{2}{\sqrt{1-x^{2}}}$.તેથી,$\frac{df}{dg} = \frac{df/dx}{dg/dx} = \frac{1}{2(1+x^{2})} \cdot \frac{\sqrt{1-x^{2}}}{2} = \frac{\sqrt{1-x^{2}}}{4(1+x^{2})}$.$x = \frac{1}{2}$ આગળ,$\frac{df}{dg} = \frac{\sqrt{1-(1/2)^{2}}}{4(1+(1/2)^{2})} = \frac{\sqrt{3/4}}{4(5/4)} = \frac{\sqrt{3}/2}{5} = \frac{\sqrt{3}}{10}$.

$x=\frac{1}{2}$ આગળ $\tan ^{-1}\left(\frac{\sqrt{1+x^{2}}-1}{x}\right)$ નું $\tan ^{-1}\left(\frac{2 x \sqrt{1-x^{2}}}{1-2 x^{2}}\right)$ ની સાપેક્ષ વિકલન શોધો.
