Solución detallada
Tenemos la ecuación
$$\sin{\left(\frac{\pi \left(x - 3\right)}{4} \right)} = \frac{5 \pi}{4}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -1
La ecuación se convierte en
$$\sin{\left(\frac{\pi x}{4} + \frac{\pi}{4} \right)} = - \frac{5 \pi}{4}$$
Como el miembro derecho de la ecuación
en el módulo =
True
pero sin
no puede ser más de 1 o menos de -1
significa que la ecuación correspondiente no tiene solución.
