"Vectorial angle" is not a standard term in mathematics. The angle between two vectors v and w is defined as the value theta such that w dot v = v times w times cosine theta. Definitions:
w and v are vectors (ordered lists of numbers) of the same dimension n (i.e. both contain n terms).
The jth term in w is denoted wj (similarly for v)
w dot v = w1v1 + w2v2 +... + wnvn
w = square root of w dot w (similarly for w)
We always choose theta to be between 0 and pi (i.e. between 0 and 180 degrees), including 0 and pi as possible values of course. If w is a positive multiple of v, theta will be zero. If w is a negative multiple of v, theta will be pi.
