[1+sen(x) + cos(x) ]^2 = 2[1+sen(x)][1+cos(x)]
[1+ sen(x)^2 + cos(x)^2 +2sen(x) +2cos(x) + 2sen(x)cos(x)] = ...................
[2+2cos(x) +2sen(x) +2sen(x)cos(x)]
por trigonométrica
sen(x)^2 + cos(x)^2 = 1
2+2sen(x) +2cos(x) + 2sen(x)cos(x) = 2+2cos(x) +2sen(x) +2sen(x)cos(x)
pasando a cada factor a restar queda = 0
respuesta = 0
