Xn * F = Yn -> Regra geral da revolta popular contra mal feitor

Provarei matematicamente o que esta acontecendo e por que eh legitimo que a revolta popular seja maior contra Lula que contra Aecio.

Temos a regra geral:

Xn * F = Yn

Xn = mal causado por alguem (n)
Yn = revolta popular contra alguem (n)
l = Lula dataset
