The dot product refers to the scalar product of all the dimensions of two vectors.

This is expressed with the symbol () [Alt+083]

 

It takes in vectors and gives out a number |

 

If the dot product is zero, then it means that the vectors have no commonality between them.

In other words, if the dot product is zero, the two vectors are perpendicular/orthogonal/normal

 

 

 

Consider a unit circle

 

 

Consider  ,
