Ha introducido [src]
cos(3*x) = 1
$$\cos{\left(3 x \right)} = 1$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(3 x \right)} = 1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$3 x = \pi n + \operatorname{acos}{\left(1 \right)}$$
$$3 x = \pi n - \pi + \operatorname{acos}{\left(1 \right)}$$
O
$$3 x = \pi n$$
$$3 x = \pi n - \pi$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$3$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3}$$
$$x_{2} = \frac{\pi n}{3} - \frac{\pi}{3}$$
