Calculate the flow of the image field...across the solid boundary bounded by the planes x = 0, y = 0 and z = 0 and by the portion of z = 2 ? x ? ycontained in the first octant. Consider the orientation of the surface at which the normal field points out.

Exercicio 5. Calcule o fluxo do campo F(x,y, =) = (x] - y'=],y] - all,43,ad. -216, 29) atraves da fronteira do solido limitado pelos planos z = 0, y = 0 e = = 0 e pela porcao de = = 2- x] - y contida no primeiro octante. Considere a orientacao da superficie na qual o campo normal aponta para fora
