{tex}\sin 2x + \cos x = 0{/tex}
=> {tex}\sin 2x = - \cos x{/tex}
=> {tex}2\sin x.\cos x = - \cos x{/tex}
=> {tex}\sin x = - {1 \over 2}{/tex}
=> {tex}\sin x = \sin \left( {\pi + {\pi \over 6}} \right){/tex}
=> {tex}\sin x = \sin {{7\pi } \over 6}{/tex}
=> {tex}x = {{7\pi } \over 6} = {210^ \circ }{/tex}
