If the vectors are parallel (angle = 0 or 180 degrees) then the length of v1 x v2 will be zero because sin(0)=sin(180)=0. In the zero case the axis does not matter and can be anything because there is no rotation round it. In the 180 degree case the axis can be anything at...
In summary: The cross product of two vectors A and B is a vector that is perpendicular to both A and B and has a magnitude equal to |A|*|B|*sin(θ) where θ is the angle between A and B. In this case, the angle between the two bonds can be calculated using the dot p...
Angle between two vectorsDefinition. The angle between two vectors, deferred by a single point, called the shortest angle at which you have to turn around one of the vectors to the position of co-directional with another vector.Basic relation. The cosine of the angle between two vectors is ...

Notably, the new algorithm has the following good properties: 1) it is free from a set of supplied reference points or weight vectors; 2) it has less algorithmic parameters; and 3) the time complexity of the algorithm is low. Given both good performance and nice properties, the suggested ...
