Hey MichelleOCallaghan.

Can you explain what you are saying and the problem questions? - October 18th 2012, 01:05 AMMichelleOCallaghanRe: Downward Flux

ii) Circulation:

C {0,0,1} to {1, pi,1}

C eq: {y=pi*x, z=1}

dr={dx, pi*dx, 0}

F={cos(y/z), -x/z*sin(y/z),xy/z^2*sin(y/z)}

F.dr = -dx [dot product and simplified]

Integral[F.dr]{0 t01} = -1
