(B) ધારો કે $	an ^{-1} \frac{3}{4} = 	heta$. તેથી $	an 	heta = \frac{3}{4}$.નિત્યસમ $\sin 	heta = \frac{	an 	heta}{\sqrt{1 + 	an^2 	heta}}$ નો ઉપયોગ કરતા,આપણને $\sin 	heta = \frac{3/4}{\sqrt{1 + (3/4)^2}} = \frac{3/4}{\sqrt{25/16}} = \frac{3/4}{5/4} = \frac{3}{5}$ મળે છે.આમ,$\left[\sin \left(	an ^{-1} \frac{3}{4}ight)ight]^2 = \left(\frac{3}{5}ight)^2 = \frac{9}{25}$.ધારો કે $	an ^{-1} \frac{4}{3} = \phi$. તેથી $	an \phi = \frac{4}{3}$.નિત્યસમ $\sin \phi = \frac{	an \phi}{\sqrt{1 + 	an^2 \phi}}$ નો ઉપયોગ કરતા,આપણને $\sin \phi = \frac{4/3}{\sqrt{1 + (4/3)^2}} = \frac{4/3}{\sqrt{25/9}} = \frac{4/3}{5/3} = \frac{4}{5}$ મળે છે.આમ,$\left[\sin \left(	an ^{-1} \frac{4}{3}ight)ight]^2 = \left(\frac{4}{5}ight)^2 = \frac{16}{25}$.બંને કિંમતોનો સરવાળો કરતા: $\frac{9}{25} + \frac{16}{25} = \frac{25}{25} = 1$.
