WebThe dot product is well defined in euclidean vector spaces, but the inner product is defined such that it also function in abstract vector space, mapping the result into the Real number space. In any case, all the important properties remain: 1. The norm (or "length") of a vector is the square root of the inner product of the vector with itself. 2. WebBy definition, orthogonal is the name given to the relationship between two vectors described when their dot product is 0. The dot product of the 0 vector with any other vector is 0, so by defintion the 0 vector is orthogonal to every other vector.

Web2 Dot Product The dot product is fundamentally a projection. As shown in Figure 1, the dot product of a vector with a unit vector is the projection of that vector in the direction given by the unit vector. This leads to the geometric formula ~v ·w~ = ~v w~ cosθ (1) for the dot product of any two vectors ~v and w~ . An immediate consequence ...
