- 1.A matrix that has only one column.
- 2.The measure of the angle that the vector forms with the positive
*x*-axis or any other horizontal line. - 3.The product of vector a with endpoint (
*x*_{a},*y*_{a}) and vector b with endpoint (*x*_{b},*y*_{b}) is equal to*x*_{a}•*x*_{b}+*y*_{a}•*y*_{b}. The product of two perpendicular vectors determined in this manner is zero. This product is denoted by vector multiplication using the symbol “•” for times. - 4.The length of a vector.
- 5.The law that is the basis for a method for adding two vectors. The two vectors with the same initial point form part of a parallelogram. The resultant or sum of the two vectors is the diagonal of the parallelogram.
- 6.The sum of two or more vectors.
- 7.Multiplication of a vector by a real number.
- 8.A directed segment. It possesses both magnitude (length) and direction.
- 9.The position of a vector drawn with its endpoint at the origin.
