2sinx (уравнение)

Найду корень уравнения: 2sinx

Вы ввели

2*sin(x) = 0

$$2 \sin{\left(x \right)} = 0$$

Подробное решение

Дано уравнение
$$2 \sin{\left(x \right)} = 0$$
- это простейшее тригонометрическое ур-ние

с изменением знака при 0

Получим:
$$2 \sin{\left(x \right)} = 0$$

Разделим обе части ур-ния на 2

Ур-ние превратится в
$$\sin{\left(x \right)} = 0$$
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left(0 \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(0 \right)} + \pi$$
Или
$$x = 2 \pi n$$
$$x = 2 \pi n + \pi$$
, где n - любое целое число
