Answer:
The Unit Vector of a vector v is given as where |v| is the magnitude or norm of the vector v.
The magnitude of a unit vector is 1
Dot product of two unit vectors is the cosine of the angle of the angle between them
The unit vector in the direction of the vector v =<1, 2=""> can be found in the following way: Magnitude of the vector v =|v| = (1+2)2
Unit vector in the direction of v is given as
Hence, the unit vector in the direction of v is =
