Question
Suppose F(x, y) = (5x + 5y, 2x + 3y) and C is the circle of radius 9 centered at the origin oriented counterclockwise.
(a) Find a vector parametric equation (t) for the circle C that starts at the point (9,0) and travels around the circle once counterclockwise for 0 < t ≤ 2m.
F(t) = 0
(b) Find the circulation of around C. (Remember that the circulation of (P,Q) around the curve C is f Pdx + Qdy.)
Circulation =
(c) Find the outward flux of across C. (Remember that the outward flux of (P,Q) across the curve C is fo-Qdc + Pdy.)
Flux =
