Orientation of the vectorThe direction of a vector is the orientation of the vector, that is, the angle it makes with the x-axis1. A vector is drawn by a line with an arrow on the top and a fixed point at the other end. The direction in which the arrowhead of the vector is directed gives the direction of the vector. For example, velocity is a vector1. The direction of a vector is the direction along which it acts, and it is specified using a unit vector2.Learn more:✕This summary was generated using AI based on multiple online sources.
