Solución
Solución detallada
Tenemos la ecuación
$$\cos{\left(x \right)} = -1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{acos}{\left(-1 \right)}$$
$$x = \pi n - \pi + \operatorname{acos}{\left(-1 \right)}$$
O
$$x = \pi n + \pi$$
$$x = \pi n$$
, donde n es cualquier número entero
