$$\sin{\left(- 3 x + \frac{\pi}{6} \right)} = \frac{\left(-1\right) \sqrt{2}}{2}$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(- 3 x + \frac{\pi}{6} \right)} = \frac{\left(-1\right) \sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$3 x + \frac{\pi}{3} = \pi n + \operatorname{acos}{\left(- \frac{\sqrt{2}}{2} \right)}$$
$$3 x + \frac{\pi}{3} = \pi n - \pi + \operatorname{acos}{\left(- \frac{\sqrt{2}}{2} \right)}$$
O
$$3 x + \frac{\pi}{3} = \pi n + \frac{3 \pi}{4}$$
$$3 x + \frac{\pi}{3} = \pi n - \frac{\pi}{4}$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{3}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$3 x = \pi n + \frac{5 \pi}{12}$$
$$3 x = \pi n - \frac{7 \pi}{12}$$
Dividamos ambos miembros de la ecuación obtenida en
$$3$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} + \frac{5 \pi}{36}$$
$$x_{2} = \frac{\pi n}{3} - \frac{7 \pi}{36}$$
