Thread: Problem:

Let C be the unit circle (r=1 or x^2+y^2=1) oriented counterclockwise,and consider the vector field F=xyi + x^2j.
Q:which portions of C contribute positively to the flux of F,which portions contribute negatively?(PS:i & j are the unitary vectors)

Too lazy to do anything but cut and paste the homework question? Sheesh.
