Дано

$$cos{left (3 x right )} = 0$$
Подробное решение
Дано уравнение
$$cos{left (3 x right )} = 0$$
– это простейшее тригонометрическое ур-ние

с изменением знака при 0

Получим:
$$cos{left (3 x right )} = 0$$
Это ур-ние преобразуется в
$$3 x = pi n + {acos}{left (0 right )}$$
$$3 x = pi n – pi + {acos}{left (0 right )}$$
Или
$$3 x = pi n + frac{pi}{2}$$
$$3 x = pi n – frac{pi}{2}$$
, где n – любое целое число
Разделим обе части полученного ур-ния на
$$3$$
получим ответ:
$$x_{1} = frac{pi n}{3} + frac{pi}{6}$$
$$x_{2} = frac{pi n}{3} – frac{pi}{6}$$

Ответ

pi
x1 = —
6

$$x_{1} = frac{pi}{6}$$

pi
x2 = —
2

$$x_{2} = frac{pi}{2}$$
