$${i}\:{think}\:{simplify}: \\ $$ $$\sqrt{\frac{\mathrm{1}}{\mathrm{2}}โ\frac{\mathrm{1}}{\mathrm{2}}\mid\mathrm{sin}\:\left(\frac{\alpha}{\mathrm{2}}\right)\mid} \\ $$ $$=\sqrt{\frac{\mathrm{1}โ\mathrm{cos}\:\left(\frac{\alpha}{\mathrm{2}}โ\frac{\pi}{\mathrm{2}}\right)}{\mathrm{2}}} \\ $$ $$=\mid\mathrm{sin}\:\left(\frac{\alpha}{\mathrm{4}}โ\frac{\pi}{\mathrm{4}}\right)\mid \\ $$ | ||
