WebWhen del operates on a scalar or vector, either a scalar or vector is returned. Because of the diversity of vector products (scalar, dot, cross) one application of del already gives rise to three major derivatives: the gradient (scalar product), divergence (dot product), and curl (cross product). Web17.2 The Product Rule and the Divergence. We now address the question: how can we apply the product rule to evaluate such things? The or "del" operator and the dot and cross product are all linear, and each partial derivative obeys the product rule..

WebThe Scalar Product in Index Notation We now show how to express scalar products (also known as inner products or dot products) using index notation. Consider the vectors~a and~b, which can be expressed using index notation as ~a = a 1ˆe 1 +a 2ˆe 2 +a 3eˆ 3 = a iˆe i ~b = b 1ˆe 1 +b 2ˆe 2 +b 3eˆ 3 = b jˆe j (9) WebTensor notation introduces one simple operational rule. It is to automatically sum any index appearing twice from 1 to 3. As such, $a_i b_j$ is simply the product of two vector components, the i th component of the ${\bf a}$ vector with the j th component of the ${\bf b}$ vector.
