Degree of freedom Definition: – The minimum number of independent variables or coordinates required for specifying the position of a dynamical system consisting of one or more particle is called Degree of freedom. For the $N$ number of particles moving freely in $d$ dimensional space degrees of freedom is represented by the following equation. $f=Nd$ …

Fourier series is an expansion of a periodic function of period $2\pi$ which is representation of a function in a series of sine or cosine such as $f(x)=a_{0}+\sum_{n=1}^{\infty }a_{n}cos(nx)+\sum_{n=1}^{\infty }b_{n}sin(nx)$ where $a_{0} $, $a_{n}$ and $b_{n}$ are constants and are known as Fourier coefficients. In applying Fourier theorem for analysis of a complex periodic function, given function must satisfy the following condition (i) It …

A ferromagnetic material has a spontaneous magnetic moment- magnetic moment even in zero applied magnetic field this means that electron spins and magnetic moments are arranged in a regular manner. Consider a paramagnet with a concentration of N ions of spin S. Given an internal interaction tending to line up the magnetic moments parallel to …
In previous article we have learned about Educational evaluation where we have written about definition, purpose and principles of evaluation. Now this article is about Continuous and Comprehensive Evaluation. Continuous And Comprehensive Evaluation:- CCE refers to a system of school-based assessment that covers all aspects of student’s development. It takes care of the assessment of …
