8sin x = 7 (уравнение)

Найду корень уравнения: 8sin x = 7

Вы ввели

8*sin(x) = 7

$$8 \sin{\left(x \right)} = 7$$

Подробное решение

Дано уравнение
$$8 \sin{\left(x \right)} = 7$$
- это простейшее тригонометрическое ур-ние

Разделим обе части ур-ния на 8

Ур-ние превратится в
$$\sin{\left(x \right)} = \frac{7}{8}$$
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{7}{8} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{7}{8} \right)} + \pi$$
Или
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{7}{8} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{7}{8} \right)} + \pi$$
, где n - любое целое число

Быстрый ответ

x1 = pi - asin(7/8)

$$x_{1} = \pi - \operatorname{asin}{\left(\frac{7}{8} \right)}$$

x2 = asin(7/8)

$$x_{2} = \operatorname{asin}{\left(\frac{7}{8} \right)}$$
