sin(3*x)-1=0

Перенесём -1 в правую часть ур-ния

с изменением знака при -1

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