Observe that the dot product of any two vectors v and w equals det ( v, J w). In words: the dot product of v and w is the orientated area of the parallelogram spanned by v and J w. WebAt its core it seems to me that the line integral of a vector field is just the sum of a bunch of dot products with one vector being the vector field and the other being the derivative vector of the [curve] That is exactly right. The reasoning behind this is more readily understood using differential geometry.

WebJun 20, 2005 · 2 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~ = j~vjjw~ jcosµ (1) for the dot product of any two vectors ~v and w~. WebGeometric interpretation of the scalar product. The product of two non zero vectors is equal to the magnitude of one of them times the projection of the other onto it. In the picture, O A ′ is the projection of the vector u → on v →.
