Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
A net is dipped in a river. Determine the flow rate of water across the net if the velocity vector field for the river is given by
= (x - y, z + y + 9, z) and the net is decribed by the equation y = V1-x - z, y 2 0, and oriented in the positive y-
direction.
(Use symbolic notation and fractions where needed.)

1. You are given a vector function A = Îx,
(a) Sketch this vector function in the x-y coordinate plane.
(b) Without doing the math, look at your sketch, and explain in words why this vector
function does or does not have a divergence.
(c) Calculate the divergence of this vector function. Is the answer a scalar or a vector?
