# Thread: flux integral

1. ## flux integral

Let $F = 5x^3I+2^3J$ and let n be the outward unit normal vector to the positively oriented circle $x^2+y^2=16$
Need help with this, I dont understand Green's Theorem, flux of F. Examples in book does not help.

Is the j component of F meant to be 2^3?

Please state Greens Theorem and then state where you get stuck in applying it.
