$$\cos{\left(\frac{8 \pi x}{6} \right)} = \frac{\sqrt{3}}{2}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(\frac{8 \pi x}{6} \right)} = \frac{\sqrt{3}}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$\frac{4 \pi x}{3} = \pi n + \operatorname{acos}{\left(\frac{\sqrt{3}}{2} \right)}$$
$$\frac{4 \pi x}{3} = \pi n - \pi + \operatorname{acos}{\left(\frac{\sqrt{3}}{2} \right)}$$
O
$$\frac{4 \pi x}{3} = \pi n + \frac{\pi}{6}$$
$$\frac{4 \pi x}{3} = \pi n - \frac{5 \pi}{6}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{4 \pi}{3}$$
obtenemos la respuesta:
$$x_{1} = \frac{3 \left(\pi n + \frac{\pi}{6}\right)}{4 \pi}$$
$$x_{2} = \frac{3 \left(\pi n - \frac{5 \pi}{6}\right)}{4 \pi}$$
