Questions and Answers
- 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 (xa, ya) and vector b with endpoint (xb, yb) is equal to xa•xb + ya•yb. 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.
