Unit Vectors. We are familiar with the unit vectors in Cartesian coordinates, where . points in the x-direction and . y-direction. Here, we will first state the general definition of a unit vector, and then extend this definition into 2D polar coordinates and 3D spherical coordinates. 2D Cartesian Coordinates. Consider a point (x, y).
Unit vectors are vectors that have a magnitude of 1 and have no units. These vectors are used to describe a direction in space. To find the unit vector of a vector, we divide each component by its magnitude. In this article, we will learn how to calculate unit vectors of vectors.
