Explanation:
To normalize a vector we calculate the vector norm (its magnitude) and scale the vector by dividing by the norm to create a unit vector.
So let:
# vec u = <<2,3,1, >> #
Then we calculate the vector norm:
# || vec u || = sqrt(2^2+3^2+1^2) #
# " " = sqrt(4+9+1) #
# " " = sqrt(14) #
Now we scale the initial vector by dividing by the norm to get:
# || hat u || = 1/sqrt(14) \ <<2,3,1, >> #
# " " = <<2/sqrt(14),3/sqrt(14),1/sqrt(14) >> #
