| $Q$. જો $\cos x+\cos y+\cos z=0=\sin x+\sin y+\sin z$ હોય,તો $\cos \frac{x-y}{2}$ ની શક્ય કિંમત | $2$. $\sqrt{2}$ |
| $R$. જો $\cos (\frac{\pi}{4}-x) \cos 2 x+\sin x \sin 2 x \sec x=\cos x \sin 2 x \sec x+\cos (\frac{\pi}{4}+x) \cos 2 x$ હોય,તો $\sec x$ ની શક્ય કિંમત | $3$. $\frac{1}{2}$ |
| $S$. જો $\cot (\sin ^{-1} \sqrt{1-x^2})=\sin (\tan ^{-1}(x \sqrt{6})), x \neq 0$ હોય,તો $x$ ની શક્ય કિંમત | $4$. $1$ |
