Sqrt(3)sinx+cosx=sqrt(2)

разделим на 2 каждый член уравнения

$\frac{\sqrt{3}}{2}sinx+\frac{1}{2}cos x =\frac{\sqrt{2}}{2}$

$\frac{\sqrt{3}}{2}=cos{\frac{\pi}{6}}\\ \frac{1}{2}=sin{\frac{\pi}{6}}\\ sin(x+\frac{\pi}{6})=\frac{\sqrt{2}}{2}\\ x+\frac{\pi}{6} = \frac{\pi}{4}+2\pi n\\ x= -\frac{\pi}{6} + \frac{\pi}{4}+2\pi n\\ x = \frac{\pi}{12}+2\pi n\\ \\ x+\frac{\pi}{6} = \pi-\frac{\pi}{4}+2\pi n\\ x+\frac{\pi}{6} = \frac{3\pi}{4}+2\pi n\\ x=-\frac{\pi}{6} + \frac{3\pi}{4}+2\pi n\\ x = \frac{7\pi}{12}+2\pi n\\$
