Let S be the part of the surface of the equation z = x + y above the triangle of vertices (0, 0), (1, 1)and (0, 1).(a) Find a parameterization for S. What is the domain of this parameterization?b) Mount the surface integral. Note: You don't need to solve the integral!The integral is in the figure

Exercicio 4. Seja S a parte da superficie de equacao z = r + y- acima do triangulo de vertices (0, 0), (1, 1) e (0, 1). (a) Encontre uma parametrization para S. Qual e o dominio dessa parametrizatio (b) Monte a integral de superficie ezds. S Observacao: Nao precisa resolver a integral
