sin(x)=-2/3 (уравнение)

Найду корень уравнения: sin(x)=-2/3

Вы ввели

sin(x) = -2/3

$$\sin{\left(x \right)} = - \frac{2}{3}$$

Подробное решение

Дано уравнение
$$\sin{\left(x \right)} = - \frac{2}{3}$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left(- \frac{2}{3} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(- \frac{2}{3} \right)} + \pi$$
Или
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{2}{3} \right)}$$
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{2}{3} \right)} + \pi$$
, где n - любое целое число

Быстрый ответ

x1 = pi + asin(2/3)

$$x_{1} = \operatorname{asin}{\left(\frac{2}{3} \right)} + \pi$$

x2 = -asin(2/3)

$$x_{2} = - \operatorname{asin}{\left(\frac{2}{3} \right)}$$

Сумма и произведение корней

сумма

0 + pi + asin(2/3) - asin(2/3)

$$- \operatorname{asin}{\left(\frac{2}{3} \right)} + \left(0 + \left(\operatorname{asin}{\left(\frac{2}{3} \right)} + \pi\right)\right)$$

=

pi

$$\pi$$

произведение

1*(pi + asin(2/3))*-asin(2/3)

$$1 \left(\operatorname{asin}{\left(\frac{2}{3} \right)} + \pi\right) \left(- \operatorname{asin}{\left(\frac{2}{3} \right)}\right)$$

=

-(pi + asin(2/3))*asin(2/3)

$$- \left(\operatorname{asin}{\left(\frac{2}{3} \right)} + \pi\right) \operatorname{asin}{\left(\frac{2}{3} \right)}$$
