Question

Помогите пожалуйста!!!!

Answer 1

Ответ:

$\sin {}^{2} (x) + \frac{ \sqrt{3} }{2} \sin(x) = \\ \sin(x) (\sin(x) + \frac{ \sqrt{3} }{2} ) = 0 \\ \\ \sin(x) = 0 \\ x1 = 180^{\circ}n \\ \\ \sin( x ) = - \frac{ \sqrt{3} }{2} \\ x2 = - 60^{\circ} + 360^{\circ}n \\ x3 = 240^{\circ} + 360^{\circ}n$
