sin(5*x) = -1
$$\sin{\left(5 x \right)} = -1$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(5 x \right)} = -1$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$5 x = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$5 x = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$5 x = 2 \pi n - \frac{\pi}{2}$$
$$5 x = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$5$$
obtenemos la respuesta:
$$x_{1} = \frac{2 \pi n}{5} - \frac{\pi}{10}$$
$$x_{2} = \frac{2 \pi n}{5} + \frac{3 \pi}{10}$$
