tan(3*x)=3

$$tan{left (3 x right )} = 3$$

Дано уравнение
$$tan{left (3 x right )} = 3$$
– это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$3 x = pi n + {atan}{left (3 right )}$$
Или
$$3 x = pi n + {atan}{left (3 right )}$$
, где n – любое целое число
Разделим обе части полученного ур-ния на
$$3$$
получим ответ:
$$x_{1} = frac{pi n}{3} + frac{1}{3} {atan}{left (3 right )}$$

atan(3)
x1 = ——-
3

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