What is the Stokes’s Theorem? || Stokes Theorem Example
Stokes’s Theorem Stokes’ theorem is a fundamental result in vector calculus that relates a surface integral over a surface S to a line integral around its boundary curve C. It is named after the Irish mathematician George Gabriel Stokes. The Read More …
Linear Transformation and Properties of Linear Transformation with Example
Introduction to Linear Transformation Linear transformation is a fundamental concept in linear algebra that describes a mapping between two vector spaces that preserves the algebraic structure of those spaces. In simpler terms, it is a mathematical function that takes vectors Read More …
Boundary Value Conditions in Electrostatics
Boundary Value Conditions in Electrostatics In electrostatics, which deals with stationary electric charges and their interactions, electric boundary conditions describe the behavior of the electric field at the interfaces between different media or regions. The two main types of boundary Read More …
