Solución

Ha introducido [src]
cos(4*x) = 1
$$\cos{\left(4 x \right)} = 1$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(4 x \right)} = 1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$4 x = \pi n + \operatorname{acos}{\left(1 \right)}$$
$$4 x = \pi n - \pi + \operatorname{acos}{\left(1 \right)}$$
O
$$4 x = \pi n$$
$$4 x = \pi n - \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$4$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{4}$$
$$x_{2} = \frac{\pi n}{4} - \frac{\pi}{4}$$
