$$\cos{\left(\frac{x}{5} \right)} = -1$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(\frac{x}{5} \right)} = -1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$\frac{x}{5} = \pi n + \operatorname{acos}{\left(-1 \right)}$$
$$\frac{x}{5} = \pi n - \pi + \operatorname{acos}{\left(-1 \right)}$$
O
$$\frac{x}{5} = \pi n + \pi$$
$$\frac{x}{5} = \pi n$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{1}{5}$$
obtenemos la respuesta:
$$x_{1} = 5 \pi n + 5 \pi$$
$$x_{2} = 5 \pi n$$
