tan(x)=-sqrt(3)/3

$$tan{left (x right )} = frac{-1 sqrt{3}}{3}$$

Дано уравнение
$$tan{left (x right )} = frac{-1 sqrt{3}}{3}$$
– это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = pi n + {atan}{left (- frac{sqrt{3}}{3} right )}$$
Или
$$x = pi n – frac{pi}{6}$$
, где n – любое целое число

-pi
x1 = —-
6

$$x_{1} = – frac{pi}{6}$$
