Homework Statement
F = <x^2 y^3 z, sin(xyz), xyz>
S is part of the cone y^2 = x^2 + z^2 that lies between y = 0 and y = 3.
Oriented in the direction of the positive y-axis.
Homework Equations
The Attempt at a Solution
I know how to do the integral, and I get the correct answer except it's the negative of the answer. My question is, what direction does "oriented in the direction of the positive y-axis" imply? I thought it was CCW, but if I do that, I get the opposite of the answer.
I am using
x = 3cos(t)
y = 3
z = 3sin(t)
My books uses
x = 3sin(t)
y = 3
z = 3cos(t)
But I'm not sure why they would use that, unless the direction of the curve is CW...
