Any vector has an associated unit vector in the same direction but having a magnitude of one. Any vector can be expressed as ascalar multipleof its unit vector. The following diagram shows how to normalize a vector or how to determine a unit vector. Scroll down the page for more examples...
Here we show that the vector a is made up of 2 "x" unit vectors and 1.3 "y" unit vectors.In 3 DimensionsLikewise we can use unit vectors in three (or more!) dimensions:Advanced topic: arranged like this the three unit vectors form a basis of 3D space. But that is not the only ...
