$$\cos{\left(x - \frac{\pi}{6} \right)} = \frac{\left(-1\right) \sqrt{3}}{2}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(x - \frac{\pi}{6} \right)} = \frac{\left(-1\right) \sqrt{3}}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x + \frac{\pi}{3} = 2 \pi n + \operatorname{asin}{\left(- \frac{\sqrt{3}}{2} \right)}$$
$$x + \frac{\pi}{3} = 2 \pi n - \operatorname{asin}{\left(- \frac{\sqrt{3}}{2} \right)} + \pi$$
O
$$x + \frac{\pi}{3} = 2 \pi n - \frac{\pi}{3}$$
$$x + \frac{\pi}{3} = 2 \pi n + \frac{4 \pi}{3}$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{3}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$x = 2 \pi n - \frac{2 \pi}{3}$$
$$x = 2 \pi n + \pi$$
