/ ___\ |\/ 3 | |-----| -cos(x) \ 2 / -------- - ------- = 0 3 3
Transportemos -sqrt(3)/6 al miembro derecho de la ecuación
cambiando el signo de -sqrt(3)/6
Dividamos ambos miembros de la ecuación en -1/3
5*pi x1 = ---- 6
7*pi x2 = ---- 6
x2 = 7*pi/6
suma
5*pi 7*pi ---- + ---- 6 6
=
2*pi
producto
5*pi 7*pi ----*---- 6 6
=
