vector
n 1: a variable quantity that can be resolved into components
2: a straight line segment whose length is magnitude and whose
orientation in space is direction
3: any agent (person or animal or microorganism) that carries
and transmits a disease; "mosquitos are vectors of malaria
and yellow fever"; "fleas are vectors of the plague"; "aphids
are transmitters of plant diseases"; "when medical scientists

to carry.]
1. Same as {Radius vector}.
[1913 Webster]

2. (Math.) A directed quantity, as a straight line, a force,

directions are the same and their magnitudes equal. Cf.
{Scalar}.
[1913 Webster]

Note: In a triangle, either side is the vector sum of the
other two sides taken in proper order; the process
finding the vector sum of two or more vectors is vector
addition (see under {Addition}).
