Solución
Solución detallada
Tenemos la ecuación
$$\sinh{\left(i z \right)} = - i$$
es la ecuación trigonométrica más simple
La ecuación se convierte en
$$\sin{\left(z \right)} = -1$$
Esta ecuación se reorganiza en
$$z = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$z = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$z = 2 \pi n - \frac{\pi}{2}$$
$$z = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
$$\sinh{\left(i z \right)} = - i$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en i
La ecuación se convierte en
$$\sin{\left(z \right)} = -1$$
Esta ecuación se reorganiza en
$$z = 2 \pi n + \operatorname{asin}{\left(-1 \right)}$$
$$z = 2 \pi n - \operatorname{asin}{\left(-1 \right)} + \pi$$
O
$$z = 2 \pi n - \frac{\pi}{2}$$
$$z = 2 \pi n + \frac{3 \pi}{2}$$
, donde n es cualquier número entero
