   2/    pi\    
cos |x + --| = 1
    \    6 /    
$$\cos^{2}{\left(x + \frac{\pi}{6} \right)} = 1$$
Solución detallada
Tenemos la ecuación
$$\cos^{2}{\left(x + \frac{\pi}{6} \right)} = 1$$
cambiamos
$$\cos^{2}{\left(x + \frac{\pi}{6} \right)} - 1 = 0$$
$$\cos^{2}{\left(x + \frac{\pi}{6} \right)} - 1 = 0$$
Sustituimos
$$w = \cos{\left(x + \frac{\pi}{6} \right)}$$
Tenemos la ecuación
$$\cos^{2}{\left(x + \frac{\pi}{6} \right)} - 1 = 0$$
Ya que la potencia en la ecuación es igual a = 2 - contiene un número par 2 en el numerador, entonces
la ecuación tendrá dos raíces reales.
Extraigamos la raíz de potencia 2 de las dos partes de la ecuación:
Obtenemos:
$$\sqrt{\left(0 w + \cos{\left(x + \frac{\pi}{6} \right)}\right)^{2}} = \sqrt{1}$$
$$\sqrt{\left(0 w + \cos{\left(x + \frac{\pi}{6} \right)}\right)^{2}} = \left(-1\right) \sqrt{1}$$
o
$$\cos{\left(x + \frac{\pi}{6} \right)} = 1$$
$$\cos{\left(x + \frac{\pi}{6} \right)} = -1$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
cosx+pi/6 = 1

Esta ecuación no tiene soluciones
Abrimos los paréntesis en el miembro izquierdo de la ecuación
cosx+pi/6 = -1

Esta ecuación no tiene soluciones
o

hacemos cambio inverso
$$\cos{\left(x + \frac{\pi}{6} \right)} = w$$
Tenemos la ecuación
$$\cos{\left(x + \frac{\pi}{6} \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
O
$$x + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{6}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \frac{\pi}{6}$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \frac{7 \pi}{6}$$
sustituimos w:
