(A) આપણને $	an A = \frac{1}{\sqrt{x(x^2+x+1)}}$ અને $	an B = \frac{\sqrt{x}}{\sqrt{x^2+x+1}}$ આપેલ છે.સૂત્ર $	an(A+B) = \frac{	an A + 	an B}{1 - 	an A 	an B}$ નો ઉપયોગ કરતા:$	an(A+B) = \frac{\frac{1}{\sqrt{x(x^2+x+1)}} + \frac{\sqrt{x}}{\sqrt{x^2+x+1}}}{1 - \frac{1}{\sqrt{x(x^2+x+1)}} \cdot \frac{\sqrt{x}}{\sqrt{x^2+x+1}}}$$= \frac{\frac{1 + x}{\sqrt{x(x^2+x+1)}}}{1 - \frac{1}{x^2+x+1}} = \frac{\frac{1+x}{\sqrt{x(x^2+x+1)}}}{\frac{x^2+x}{x^2+x+1}} = \sqrt{x+1+\frac{1}{x}}$.અહીં $	an C = \sqrt{\frac{x^2+x+1}{x^3}} = \frac{1}{x}\sqrt{x^2+x+1}$.ગણતરી કરતા $A+B=C$ મળે છે.

જો $\tan A=\frac{1}{\sqrt{x(x^2+x+1)}}, \tan B=\frac{\sqrt{x}}{\sqrt{x^2+x+1}}$ અને $\tan C=\sqrt{x^{-1}+x^{-2}+x^{-3}}$ હોય,તો:
