Question

СРОЧНО ПОМОГИТЕ С
$\sin(12) \times \cos(12) - \frac{1}{2} \sin(24 )$
ДЗ!!!

Answer 1

$\star \; \; 2sin\alpha \cdot cos\alpha =sin2\alpha \; \; \to \; \; sin\alpha \cdot cos\alpha =\frac{1}{2}\cdot sin2\alpha \; \; \star \\\\\\sin12\cdot cos12- \frac{1}{2}sin24=\frac{1}{2}\cdot sin24-\frac{1}{2}\cdot sin24=0$
