Solución
Solución detallada
Tenemos la ecuación
$$\sin{\left(6 x \right)} = - \frac{1}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$6 x = 2 \pi n + \operatorname{asin}{\left(- \frac{1}{2} \right)}$$
$$6 x = 2 \pi n - \operatorname{asin}{\left(- \frac{1}{2} \right)} + \pi$$
O
$$6 x = 2 \pi n - \frac{\pi}{6}$$
$$6 x = 2 \pi n + \frac{7 \pi}{6}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$6$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} - \frac{\pi}{36}$$
$$x_{2} = \frac{\pi n}{3} + \frac{7 \pi}{36}$$
$$\sin{\left(6 x \right)} = - \frac{1}{2}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$6 x = 2 \pi n + \operatorname{asin}{\left(- \frac{1}{2} \right)}$$
$$6 x = 2 \pi n - \operatorname{asin}{\left(- \frac{1}{2} \right)} + \pi$$
O
$$6 x = 2 \pi n - \frac{\pi}{6}$$
$$6 x = 2 \pi n + \frac{7 \pi}{6}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$6$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} - \frac{\pi}{36}$$
$$x_{2} = \frac{\pi n}{3} + \frac{7 \pi}{36}$$
