$$\sin{\left(6 x + \pi \right)} = \frac{\left(-1\right) \sqrt{2}}{2}$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(6 x + \pi \right)} = \frac{\left(-1\right) \sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
La ecuación se convierte en
$$\sin{\left(6 x \right)} = \frac{\sqrt{2}}{2}$$
Esta ecuación se reorganiza en
$$6 x = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)}$$
$$6 x = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)} + \pi$$
O
$$6 x = 2 \pi n + \frac{\pi}{4}$$
$$6 x = 2 \pi n + \frac{3 \pi}{4}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$6$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} + \frac{\pi}{24}$$
$$x_{2} = \frac{\pi n}{3} + \frac{\pi}{8}$$
$$\sin{\left(6 x + \pi \right)} = \frac{\left(-1\right) \sqrt{2}}{2}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -1
La ecuación se convierte en
$$\sin{\left(6 x \right)} = \frac{\sqrt{2}}{2}$$
Esta ecuación se reorganiza en
$$6 x = 2 \pi n + \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)}$$
$$6 x = 2 \pi n - \operatorname{asin}{\left(\frac{\sqrt{2}}{2} \right)} + \pi$$
O
$$6 x = 2 \pi n + \frac{\pi}{4}$$
$$6 x = 2 \pi n + \frac{3 \pi}{4}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$6$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{3} + \frac{\pi}{24}$$
$$x_{2} = \frac{\pi n}{3} + \frac{\pi}{8}$$
