WebMar 2, 2024 · Dot product is defined as the product of the Euclidean magnitude of two vectors and the cosine of the angle connecting them. The dot product of vectors gains various applications in geometry, engineering, mechanics, and astronomy. Both definitions are similar when operating with Cartesian coordinates. WebMultiplication of vectors is of two types. A vector has both magnitude and direction and based on this the two ways of multiplication of vectors are the dot product of two vectors and the cross product of two vectors. The dot product of two vectors is also referred to as scalar product, as the resultant value is a scalar quantity.

WebJan 16, 2024 · The dot product of v and w, denoted by v ⋅ w, is given by: (1.3.1) v ⋅ w = v 1 w 1 + v 2 w 2 + v 3 w 3. Similarly, for vectors v = ( v 1, v 2) and w = ( w 1, w 2) in R 2, the dot product is: (1.3.2) v ⋅ w = v 1 w 1 + v 2 w 2. Notice that the dot product of two vectors is a scalar, not a vector.
