Dot Product
The mathematical Dot Product of two vectors creates a relationship between two vectors and a number, referred to as Scalar. Hence, the Dot Product can also be referred to as a scalar product. Interesting for us are the values, i.e., the lengths of the vectors and the angles confined between the vectors. The Dot Product is the result of the multiplication of both vectors with the cosine of the confined angles. The Dot Product of Vector 1 and Vector 2 = vector length 1 * vector length 2 * Cos(angle between Vector 1 and Vector 2).
两个向量的数学点积在两个向量和一个数字之间创建了一种关系，称为 Scalar。因此，点积也可以称为标积。我们感兴趣的是值，即矢量的长度和矢量之间的夹角。点积是两个矢量与有限角的余弦相乘的结果。矢量1和矢量2的点积 = 矢量长度1 * 矢量长度2 * Cos (矢量1和矢量2之间的夹角)。
