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.
How do you graph the vector field F = ⟨ƒ(x, y), g(x, y)⟩?
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
v = (x-y, z + y + 3, z²) and the net is decribed by the equation y = √1-x²-2², y ≥ 0, and oriented in the positive y-
direction.
(Use symbolic notation and fractions where needed.)

flow rate of water across the net if the
velocity vector field for the river is given
by v=(x-y,z+y+7,z2) and the net is
decribed by the equation y=1-x2-z2, y20,
and oriented in the positive y- direction.
