(C) આપેલ સમીકરણ: $\sin ^{-1} x + \sin ^{-1}(1-x) = \cos ^{-1} x$ કારણ કે $\cos ^{-1} x = \frac{\pi}{2} - \sin ^{-1} x$,તેથી: $\sin ^{-1}(1-x) = \frac{\pi}{2} - \sin ^{-1} x - \sin ^{-1} x = \frac{\pi}{2} - 2\sin ^{-1} x$ બંને બાજુ $\sin$ લેતા: $1-x = \sin(\frac{\pi}{2} - 2\sin ^{-1} x) = \cos(2\sin ^{-1} x)$ નિત્યસમ $\cos(2	heta) = 1 - 2\sin^2 	heta$ નો ઉપયોગ કરતા,જ્યાં $	heta = \sin ^{-1} x$: $1-x = 1 - 2(\sin(\sin ^{-1} x))^2$ $1-x = 1 - 2x^2$ $2x^2 - x = 0$ $x(2x - 1) = 0$ આમ,$x = 0$ અથવા $x = \frac{1}{2}$. કિંમતો ચકાસતા: $x=0$ માટે: $\sin ^{-1} 0 + \sin ^{-1} 1 = 0 + \frac{\pi}{2} = \frac{\pi}{2}$ અને $\cos ^{-1} 0 = \frac{\pi}{2}$. (માન્ય) $x=\frac{1}{2}$ માટે: $\sin ^{-1} \frac{1}{2} + \sin ^{-1} \frac{1}{2} = \frac{\pi}{6} + \frac{\pi}{6} = \frac{\pi}{3}$ અને $\cos ^{-1} \frac{1}{2} = \frac{\pi}{3}$. (માન્ય) તેથી,$x \in \{0, \frac{1}{2}\}$.

જો $\sin ^{-1} x+\sin ^{-1}(1-x)=\cos ^{-1} x$ હોય,તો $x \in$
