1-cos(x)=0

Дано

$$- \cos{\left (x \right )} + 1 = 0$$
Подробное решение
Дано уравнение
$$- \cos{\left (x \right )} + 1 = 0$$
— это простейшее тригонометрическое ур-ние

Перенесём 1 в правую часть ур-ния

с изменением знака при 1

Получим:
$$- \cos{\left (x \right )} = -1$$

Разделим обе части ур-ния на -1

Ур-ние превратится в
$$\cos{\left (x \right )} = 1$$
Это ур-ние преобразуется в
$$x = \pi n + {acos}{\left (1 \right )}$$
$$x = \pi n — \pi + {acos}{\left (1 \right )}$$
Или
$$x = \pi n$$
$$x = \pi n — \pi$$
, где n — любое целое число

Ответ
Читайте также  2*(log(13)*sqrt(x)-1)*e^(log(13)*sqrt(x))*1/(log(13)^2) если x=1/3 (упростите выражение)
$$x_{1} = 0$$

x2 = 2*pi

$$x_{2} = 2 \pi$$
