$$\cos{\left(3 x \right)} \cos{\left(\frac{1}{2} + \frac{\pi}{6} \right)} = \frac{\sin{\left(\pi \right)} \sin{\left(3 x \right)}}{6}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(3 x \right)} \cos{\left(\frac{1}{2} + \frac{\pi}{6} \right)} = \frac{\sin{\left(\pi \right)} \sin{\left(3 x \right)}}{6}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en cos(1/2 + pi/6)

La ecuación se convierte en
$$\cos{\left(3 x \right)} = 0$$
Esta ecuación se reorganiza en
$$3 x = \pi n + \operatorname{acos}{\left(0 \right)}$$
$$3 x = \pi n - \pi + \operatorname{acos}{\left(0 \right)}$$
O
$$3 x = \pi n + \frac{\pi}{2}$$
$$3 x = \pi n - \frac{\pi}{2}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$3$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} + \frac{\pi}{6}$$
$$x_{2} = \frac{\pi n}{3} - \frac{\pi}{6}$$
