Scalar and Vector fields

In this article, learn what are Scalar and Vector fields. We know that many physical quantities like temperature, electric or gravitational field, etc. have different values at different points in space, for example, the electric field of a point charge is large near the charge and it decreases as we got farther away from the …

Fourier Series formula sheet

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 an complex periodic function , given function must satisfy following condition (i) It …

Spherical coordinates system (Spherical polar coordinates)

This article is about Spherical Polar co-ordinates and is aimed for First year physics students and also for those appearing for exams like JAM/GATE etc.
The spherical polar coordinates represent the coordinates of points on the surface of a sphere in a co-variant form. The coordinates of the point P in this system is represented by the radial vector r which is the distance from the origin to the point, the polar or

The Critical approach to curriculum

This article is about the critical approach to curriculum. Those who embrace the critical approach to curriculum consider education as a political act, one that should function in liberated ways (Piner 1978). This is a topic under subject knowledge and curriculum for B.Ed. I will give links for further reference at the end of the article. …
