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