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.
For vector field F = (-2y, y), y > 0. Find all points P such that the amount of fluid flowing into P equals the amount of fluid flowing out of P. Write down the equation these points satisfy.
