$$2 \sin{\left(\frac{4 x - \pi}{3} \right)} = \sqrt{3}$$
Solución detallada
Tenemos la ecuación
$$2 \sin{\left(\frac{4 x - \pi}{3} \right)} = \sqrt{3}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -2

La ecuación se convierte en
$$\cos{\left(\frac{4 x}{3} + \frac{\pi}{6} \right)} = - \frac{\sqrt{3}}{2}$$
Esta ecuación se reorganiza en
$$\frac{4 x}{3} + \frac{\pi}{6} = \pi n + \operatorname{acos}{\left(- \frac{\sqrt{3}}{2} \right)}$$
$$\frac{4 x}{3} + \frac{\pi}{6} = \pi n - \pi + \operatorname{acos}{\left(- \frac{\sqrt{3}}{2} \right)}$$
O
$$\frac{4 x}{3} + \frac{\pi}{6} = \pi n + \frac{5 \pi}{6}$$
$$\frac{4 x}{3} + \frac{\pi}{6} = \pi n - \frac{\pi}{6}$$
, donde n es cualquier número entero
Transportemos
$$\frac{\pi}{6}$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$\frac{4 x}{3} = \pi n + \frac{2 \pi}{3}$$
$$\frac{4 x}{3} = \pi n - \frac{\pi}{3}$$
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{4}{3}$$
obtenemos la respuesta:
$$x_{1} = \frac{3 \pi n}{4} + \frac{\pi}{2}$$
$$x_{2} = \frac{3 \pi n}{4} - \frac{\pi}{4}$$
