El profesor se sorprenderá mucho al ver tu solución correcta😉
Transportemos -1 al miembro derecho de la ecuación
cambiando el signo de -1
Dividamos ambos miembros de la ecuación en 3
x1 = -acos(1/3) + 2*pi
x2 = acos(1/3)
x2 = acos(1/3)
suma
-acos(1/3) + 2*pi + acos(1/3)
=
2*pi
producto
(-acos(1/3) + 2*pi)*acos(1/3)
=
(-acos(1/3) + 2*pi)*acos(1/3)
(-acos(1/3) + 2*pi)*acos(1/3)
