Fourier Analysis 1: Definition of the Fourier Series


We begin our study on the work of Joseph Fourier (1768-1830) with the definition of the Fourier Series - a way of expressing functions as infinite sums or integrals or trigonometry functions. Please check out www.gaussianmath.com for a deeper look into this or other mathematics topics.

How to compute a Fourier series: an example


This video is a demonstration on how to compute a Fourier series of a simple given function. I discuss how to calculate the Fourier coefficients through integration and the simplifications involved. Fourier series are an important area of applied mathematics, engineering and physics that are used in solving partial differential equations, such as the heat equation and the wave equation. Fourier series are named after J. Fourier, a French mathematician who was the first to correctly model the diffusion of heat. Fourier series are seen in 2nd-year university mathematics.

Lecture 2 | The Fourier Transforms and its Applications


Lecture by Professor Brad Osgood for the Electrical Engineering course, The Fourier Transforms and its Applications (EE 261). Professor Osgood's lecture addresses the question- How can we use such simple functions, sin(t) and cos(t) to model such periodic phenomenon? He takes the students through the first steps in analyzing general periodic phenomenon. The Fourier transform is a tool for solving physical problems. In this course the emphasis is on relating the theoretical principles to solving practical engineering and science problems.

Link to fanfiction: www.fanfiction.net Link to fanfiction [in Hungarian]: fanfic.hu Storyline: Time traveling to Hogwarts in the year 1944 changed more than just the future, but the past as well. Hermione Granger has turned into Hermione Grindelwald, the only heir to the Dark wizard Grindelwald; but something was different about Hermione than Harry, Ginny and Ron. Grindelwald had wiped her memory, and it wasn't until she met Riddle that they came back. Hermione must change Riddle's ways before he's Voldemort, but Dumbledore didn't mention the flaws in the time travel equation he had used. Joseph Fourier had been brutally murdered when he had finished his equation, and when they found him, his work was missing, leaving the equation flawed. But what was the flaw, and would it stop Hermione, Harry, Ron and Ginny from destroying Voldemort? Exactly how many flaws are there?
