The standard unit vectors are the special unit vectors that are parallel to the coordinate axes pointing toward positive values of the coordinate. Two dimensions The standard unit vectors in two dimensions.Definition The vectors veci (1 0 0) vecj (0 1 0) and veck (0 0 1) are said to be Standard Unit Vectors that is a vector that runs on either the x y or z-axis and has a magnitude of 1 that is mid mid veci mid mid mid mid vecj mid mid mid mid veck mid mid 1.By definition the standard basis is a sequence of orthogonal unit vectors. In other words it is an ordered and orthonormal basis. However an ordered orthonormal basis is not necessarily a standard basis. For instance the two vectors representing a 30 rotation of the 2D standard basis described above i.e.

Unit vectors are any vector u where u 1 The standard unit vectors are the unit vectors that are parallel to the coordinate axes. ijk if you use that notation or (100) (010) (001) in mathbb R3 if you prefer.The unit vectors 1 0 and 0 1 are special unit vectors called standard unit vectors and are represented by the vectors i and j as follows i 1 0 j 0 1 Any vector in a plane can be written using these standard unit vectors.06.05.2015 After watching this lesson you will be able to explain what standard basis vectors (otherwise known as unit vectors) are and how they are useful.

To find the unit vector u of the vector you divide that vector by its magnitude as follows Note that this formula uses scalar multiplication because the numerator is a vector and the denominator is a scalar.A unit vector in 3 was called a right versor by W. R. Hamilton as he developed his quaternions 4. In fact he was the originator of the term vector as every quaternion has a scalar part s and a vector part v. If v is a unit vector in 3 then the square of v in quaternions is 1.
