\hspace{-0.6 cm}$Here $\sqrt{1+\sin 2} = \sqrt{\sin^21+\cos^2 1+2\sin 1\cdot \cos 1}=\left|\sin 1+\cos 1\right|$\\\\So we get $\sqrt{1+\sin 2}$ = \sin 1+\cos 1.$\\\\$Now Using $\sqrt{\sin 1}>\sin 1$ and $\cos 1>\cos 1\;,$\\\\ Bcz $\sin 1,\cos 1,\sqrt{\sin 1},\sqrt{\cos 1}\in \left(0,1\right)$\\\\So $\sin 1+\cos 1=\sqrt{1+\sin 1}<\sqrt{\sin 1}+\sqrt{\cos 1}$ and Here $1^{c}\approx 57^0$
