Question

how do we represent a unit vector​

Answer 1

Explanation:

The notation represents the norm, or magnitude, of vector v. The basic unit vectors are i = (1, 0) and j = (0, 1) which are of length 1 and have directions along the positive x-axis and y-axis respectively. To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector.

Answer 2

The notation represents the norm,or magnitude of vector v. The basic unit vector are i=(1,0) and j=(0,1)which are of length 1 and have directions along the positive x-axis and y-axis respectively. To find a unit vector with the same direction as a given vector, we divide by the magnitude of the vector .
