standard basis vectorsthe vector that is i 1 00

Question

Standard Basis Vectors

The vector that is, i = (1, 0,0) is called a standard basis vector.  In three dimensional (3D) space there are three standard basis vectors,

i^→ = (1, 0, 0)

j^→ = (0,1, 0)

k^→ = (0, 0,1)

In two dimensional spaces (2D) there are two standard basis vectors,

i^→ = (1, 0)

j^→ = (0,1)

Notice that standard basis vectors are as well unit vectors.
