    sin(x)=23\sin{\left(x \right)} = \frac{\sqrt{2}}{3}
    Подробное решение
    Дано уравнение
    sin(x)=23\sin{\left(x \right)} = \frac{\sqrt{2}}{3}
    - это простейшее тригонометрическое ур-ние
    Это ур-ние преобразуется в
    x=2πn+asin(23)x = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{3} \right)}
    x=2πnasin(23)+πx = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{3} \right)} + \pi
    Или
    x=2πn+asin(23)x = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{3} \right)}
    x=2πnasin(23)+πx = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{3} \right)} + \pi
    , где n - любое целое число
