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