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 …
This article is about educational evaluation, its definition, purpose, and principles. Let us first begin with basic definitions of test, measurement, and evaluation. 1. What is Test:- In the classroom situation, the word ‘test’ means to judge the knowledge understanding and intelligence of the students. Tests can be held after completing the chapter. A teacher …
