tan(x)=-1/3

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

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

$$x_{1} = – {atan}{left (frac{1}{3} right )}$$
