Divergence Theorem: Find Outward Flux of F (x3,x2y,xy)

Click For Summary
SUMMARY

The discussion focuses on applying the Divergence Theorem to calculate the outward flux of the vector field F = (x³, x²y, xy) through the surface of the solid defined by the inequalities 0 < y < 5 - z and 0 < z < 4 - x². The correct outward flux value is determined to be 4608/35. Participants emphasize the importance of calculating the divergence ∇ · F and suggest that setting up the triple integral without integrating in the z direction first simplifies the process.

Another question of a practice test.
How do I use the Divergence theorem to find the outward flux of the field F = (x3,x2y,xy) out through the surface of the solid U = (x,y,z): 0 < y < 5-z, 0 < z < 4-x2. The answer is 4608/35.

What are you stuck on? You can calculate \nabla \cdot F, right?

Have you sketched the volume? Do you see why the triple integral is easiest to set up if you don't integrate in the z direction first?
 
I got it. SWEET.
