sin7x=1 (уравнение)

Найду корень уравнения: sin7x=1

Вы ввели

sin(7*x) = 1

$$\sin{\left(7 x \right)} = 1$$

Подробное решение

Дано уравнение
$$\sin{\left(7 x \right)} = 1$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$7 x = 2 \pi n + \operatorname{asin}{\left(1 \right)}$$
$$7 x = 2 \pi n - \operatorname{asin}{\left(1 \right)} + \pi$$
Или
$$7 x = 2 \pi n + \frac{\pi}{2}$$
$$7 x = 2 \pi n + \frac{\pi}{2}$$
, где n - любое целое число
Разделим обе части полученного ур-ния на
$$7$$
получим ответ:
$$x_{1} = \frac{2 \pi n}{7} + \frac{\pi}{14}$$
$$x_{2} = \frac{2 \pi n}{7} + \frac{\pi}{14}$$
