Question

2 sin (x+пи/6)《 Корень 3

Answer 1

$2sin(x+ frac{ pi }{6})leq sqrt{3} \\ sin(x+ frac{ pi }{6})leq sqrt{3}/2\\-4 pi /3+2 pi n leq x+ frac{ pi }{6} leq pi /3+2 pi n, nin Z\\-4 pi /3- pi /6+2 pi n leq x leq pi /3- pi /6+2 pi n, nin Z\\-9 pi /6+2 pi n leq x leq pi /6+2 pi n, nin Z\\-3 pi /2+2 pi n leq x leq pi /6+2 pi n, nin Z$
