(A) આપણે સૂત્ર $	an ^{-1} A - 	an ^{-1} B = 	an ^{-1} \left( \frac{A-B}{1+AB} ight)$ નો ઉપયોગ કરીશું.ધારો કે $A = \frac{x}{y}$ અને $B = \frac{x-y}{x+y}$.$	an ^{-1}\left(\frac{x}{y}ight)-	an ^{-1}\left(\frac{x-y}{x+y}ight) = 	an ^{-1}\left[\frac{\frac{x}{y}-\frac{x-y}{x+y}}{1+\left(\frac{x}{y}ight)\left(\frac{x-y}{x+y}ight)}ight]$$= 	an ^{-1}\left[\frac{\frac{x(x+y)-y(x-y)}{y(x+y)}}{\frac{y(x+y)+x(x-y)}{y(x+y)}}ight]$$= 	an ^{-1}\left(\frac{x^{2}+xy-xy+y^{2}}{xy+y^{2}+x^{2}-xy}ight)$$= 	an ^{-1}\left(\frac{x^{2}+y^{2}}{x^{2}+y^{2}}ight) = 	an ^{-1}(1) = \frac{\pi}{4}$.
