vectorsCounterclock​wiseAngle

Calculate angle between 2 vectors, assuming a counterclockwise separation.

Using this function, you can calculate the angle between 2 2D vectors assuming the 'second' vector has travelled in a counterclockwise radius about the first vector. This function also assumes that the object of interest does not have a counterclockwise angular displacement of more than 360º.

This is useful for calculating counterclockwise angular displacement.

The output is in degrees, from 0-360º.
