WebJan 16, 2024 · 4.6: Gradient, Divergence, Curl, and Laplacian. In this final section we will establish some relationships between the gradient, divergence and curl, and we will also introduce a new quantity called the Laplacian. We will then show how to write these quantities in cylindrical and spherical coordinates. WebDefinition. Formal ist der Nabla-Operator ein Vektor, dessen Komponenten die partiellen Ableitungsoperatoren sind: = (, …,) Er kann dabei sowohl als Spalten-Vektor (zum Beispiel grad) als auch als Zeilen-Vektor (zum Beispiel div) auftreten. Im dreidimensionalen kartesischen Koordinatensystem schreibt man auch: = (,,) = + + Dabei sind , und die …
4.6: Gradient, Divergence, Curl, and Laplacian
WebSince the gradient of a function gives a vector, we can think of \(\grad f: \R^3 \to \R^3\) as a vector field. Thus, we can apply the \(\div\) or \(\curl\) operators to it. Similarly, \(\div F\) …WebDivergencija glatke funkcije vektorskog polja F = Fx i + Fy j + Fz k je definisana kao skalarna funkcija: Iako je izražena preko koordinata, rezultat je invarijanta pri ortogonalnim transformacijama .
