Подробное решение
Дано уравнение
$$\sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)} = \frac{1}{2}$$
преобразуем
$$\sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)} - \frac{1}{2} = 0$$
$$\sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)} - \frac{1}{2} = 0$$
Сделаем замену
$$w = \sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)}$$
Переносим свободные слагаемые (без w)
из левой части в правую, получим:
$$w = \frac{1}{2}$$
Получим ответ: w = 1/2
делаем обратную замену
$$\sin{\left(\sin{\left(\sin{\left(x \right)} \right)} \right)} = w$$
подставляем w:
