### 5.41.2 Normalize a vector : normalize
unitV

normalize or unitV takes as argument a vector.

normalize or unitV normalizes this vector for the
l^{2} norm
(the square root of the sum of the squares of its coordinates).

Input :

normalize([3,4,5])

Output :

[3/(5*sqrt(2)),4/(5*sqrt(2)),5/(5*sqrt(2))]

Indeed : x=3, y=4, z=5 and 50=|x|^{2}+|y|^{2}+|z|^{2}.
