El profesor se sorprenderá mucho al ver tu solución correcta😉
Transportemos sin(y) al miembro derecho de la ecuación
cambiando el signo de sin(y)
x1 = pi + I*im(asin(sin(y))) + re(asin(sin(y)))
x2 = -re(asin(sin(y))) - I*im(asin(sin(y)))
x2 = -re(asin(sin(y))) - i*im(asin(sin(y)))
suma
pi + I*im(asin(sin(y))) + re(asin(sin(y))) + -re(asin(sin(y))) - I*im(asin(sin(y)))
=
pi
producto
(pi + I*im(asin(sin(y))) + re(asin(sin(y))))*(-re(asin(sin(y))) - I*im(asin(sin(y))))
=
-(I*im(asin(sin(y))) + re(asin(sin(y))))*(pi + I*im(asin(sin(y))) + re(asin(sin(y))))
-(i*im(asin(sin(y))) + re(asin(sin(y))))*(pi + i*im(asin(sin(y))) + re(asin(sin(y))))
