## PhoenixFire 2 years ago Evaluate the surface integral: $\iint _{ S }^{ }{ \vec { F } \cdot \vec { dS } }$ Vector field: $\vec { F } =<y,z-y,x>$ Surface 'S': Tetrahedon $(0,0,0),(3,0,0),(0,3,0),(0,0,3)$ How do I do this? Do I need to evaluate each of the four surfaces separately and add them together?
