Question

2sin(x/2+П/2)-sqrt(3)=0 Решите,пожалуйста,срочно!!!

Answer 1

$2sin( frac{x}{2} + frac{pi}{2} )-sqrt{3}=0 \2cos (frac{x}{2} )=sqrt{3} \cos(frac{x}{2} )= frac{sqrt{3}}{2} \frac{x}{2}= frac{pi}{6} +2pi n, n in Z \x_1=frac{pi}{3} +4pi n, n in Z \frac{x}{2}= -frac{pi}{6} +2pi n, n in Z \x_2=-frac{pi}{3} +4pi n, n in Z$
