Vector2dMultiply Method (Vector2d, Vector2d)
(Provided for languages that do not support operator overloading. You can use the * operator otherwise)
public static double Multiply( Vector2d vector1, Vector2d vector2 )
Public Shared Function Multiply ( vector1 As Vector2d, vector2 As Vector2d ) As Double
This value equals v1.Length * v2.Length * cos(alpha), where alpha is the angle between vectors.
