Similarity and Distance Metrics: The dot product of two vectors is a measure of their similarity. When two vectors have a high dot product, it means they are more similar to each other. Similarly, the dot product can be used to calculate the distance between two vectors. 计算两个向量的距离...

Solution:a·b= 1 · 4 + 2 · 8 = 4 + 16 = 20. Example 2.Find the dot product of vectorsaandb, if their magnitudes is |a| = 3, |b| = 6, and the angle between the vectors is equal to 60˚. Solution:a·b= |a| · |b|cos α= 3 · 6 ·cos60˚ = 9. ...
The cross product only works in 3D. It takes two vectors as inputv1andv2, and returns a vectorc. The returned vector will be perpendicular to both the input vectors. The length of the vector is equal to the product of the lengths of the input vectors and the sine of the angle between...
