## Homework Statement

find the field's F flow where F = (y,-z,2) through the surface S where S is 4x+2y+z=6 and x,y,z>=0

## The Attempt at a Solution

we know that

we know F

N is the derivative of 4x+2y+z-6 = g(x)

actually it's N = (dg/dx,dg/dy,dg/dz)

now what i want to ask is how to find the limits of the integral i mean from what point to what point i should integrate

what I can think of is because x,y,z are bigger than 0 hence they are possitive

we will have the same points for dy and dx which will be from 0 to +oo

so can i just say

find the integral and then take the limit using xn -> oo and yn -> oo?

thanks in advance

edit: but i have a z, what am i going to do with z?
