Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(x \right)} = \frac{2}{7}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{2}{7} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{2}{7} \right)} + \pi$$
O
$$x = 2 \pi n + \operatorname{asin}{\left(\frac{2}{7} \right)}$$
$$x = 2 \pi n - \operatorname{asin}{\left(\frac{2}{7} \right)} + \pi$$
, donde n es cualquier número entero

x1 = pi - asin(2/7)
$$x_{1} = \pi - \operatorname{asin}{\left(\frac{2}{7} \right)}$$
x2 = asin(2/7)
$$x_{2} = \operatorname{asin}{\left(\frac{2}{7} \right)}$$
x2 = asin(2/7)
