2*sin(x)-1=0 (уравнение)

Найду корень уравнения: 2*sin(x)-1=0

Вы ввели

2*sin(x) - 1 = 0

$$2 \sin{\left (x \right )} - 1 = 0$$

Подробное решение

Дано уравнение
$$2 \sin{\left (x \right )} - 1 = 0$$
- это простейшее тригонометрическое ур-ние

Перенесём -1 в правую часть ур-ния

с изменением знака при -1

Получим:
$$2 \sin{\left (x \right )} = 1$$

Разделим обе части ур-ния на 2

Ур-ние превратится в
$$\sin{\left (x \right )} = \frac{1}{2}$$
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left (\frac{1}{2} \right )}$$
$$x = 2 \pi n - \operatorname{asin}{\left (\frac{1}{2} \right )} + \pi$$
Или
$$x = 2 \pi n + \frac{\pi}{6}$$
$$x = 2 \pi n + \frac{5 \pi}{6}$$
, где n - любое целое число
