Solución

Ha introducido [src]
sin(x) = -9/5
sin(x)=95\sin{\left(x \right)} = - \frac{9}{5}
Solución detallada
Tenemos la ecuación
sin(x)=95\sin{\left(x \right)} = - \frac{9}{5}
es la ecuación trigonométrica más simple
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.
