sinx-1/2=0 (уравнение)

Найду корень уравнения: sinx-1/2=0

Вы ввели

sin(x) - 1/2 = 0

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

Подробное решение

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

Перенесём -1/2 в правую часть ур-ния

с изменением знака при -1/2

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