Differential Operators: Divergence Operator and Scalar Field

This lecture covers the concept of differential operators, focusing on the divergence operator of a vector field in three-dimensional space. The instructor explains how to compute the divergence of a given vector field and provides examples to illustrate the calculations. Additionally, the Laplacian operator is introduced, defining its role in scalar fields within an open domain. The lecture emphasizes the practical application of these operators in analyzing vector and scalar fields.
