sin(5x)=0 (уравнение)

Найду корень уравнения: sin(5x)=0

Вы ввели

sin(5*x) = 0

$$\sin{\left(5 x \right)} = 0$$

Подробное решение

Дано уравнение
$$\sin{\left(5 x \right)} = 0$$
- это простейшее тригонометрическое ур-ние

с изменением знака при 0

Получим:
$$\sin{\left(5 x \right)} = 0$$
Это ур-ние преобразуется в
$$5 x = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$5 x = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
Или
$$5 x = 2 \pi n$$
$$5 x = 2 \pi n + \pi$$
, где n - любое целое число
Разделим обе части полученного ур-ния на
$$5$$
получим ответ:
$$x_{1} = \frac{2 \pi n}{5}$$
$$x_{2} = \frac{2 \pi n}{5} + \frac{\pi}{5}$$

Быстрый ответ

x1 = 0
