## How To Find Direction Vector Of A Line

To show the direction of a 3D vector, you can calculate a unit vector, which is a vector with a magnitude of one that gives the direction of the original vector. To find the components of the unit

- Example 2. According to Stroud and Booth (2013)* “If the position vectors of and are and respectively, find and determine its direction cosines.”
- Let P be the point with coordinates (x 0, y 0) and let the given line have equation ax + by + c = 0. Also, let Q = (x 1, y 1) be any point on this line and n the vector (a, b) starting at point Q.
- A line of given length and pointing along a given direction, such as an arrow, is the typical representation of a vector. Typical notation to designate a vector is a boldfaced character, a character with and arrow on it, or a character with a line under it (i.e., ).
