sinx=1/3 (уравнение)

Найду корень уравнения: sinx=1/3

Вы ввели

sin(x) = 1/3

$$\sin{\left(x \right)} = \frac{1}{3}$$

Подробное решение

Дано уравнение
$$\sin{\left(x \right)} = \frac{1}{3}$$
- это простейшее тригонометрическое ур-ние
Это ур-ние преобразуется в
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{3} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{3} \right)} + \pi$$
Или
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{1}{3} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{1}{3} \right)} + \pi$$
, где n - любое целое число

Быстрый ответ

x1 = pi - asin(1/3)

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

x2 = asin(1/3)

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

Сумма и произведение корней

сумма

0 + pi - asin(1/3) + asin(1/3)

$$\operatorname{asin}{\left(\frac{1}{3} \right)} + \left(0 + \left(\pi - \operatorname{asin}{\left(\frac{1}{3} \right)}\right)\right)$$

=

pi

$$\pi$$

произведение

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

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

=

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

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