FOURIER SERIES AND IT'S EXPANSION

                 FOURIER SERIES AND IT'S EXPANSION
The representation of a function in the form of a series is fairly common practice in mathematics. 

The Fourier series is used to expand the periodic functions. Periodic functions are the functions which repeats after some interval of period.
 Sinx, cosx, cosecx, secx  has the period of 2π. While tanx and cotx have the period of π.

Linear Algebra: Matrix Eigenvalue Problems "Mathematics is the music of reason"                                            - Sylvester Introduction to matrix:   Generally, a matrix is nothing but a rectangular array of objects. These matrices can be visualised in day - to - day applications where we use matrices to represent a military parade or a school assembly or vegetation. In lower classes we studied about the different types of matrix and determinant of a matrix. Now in this chapter the newly introduced term called Eigenvalue.  A matrix Eigenvalue problem considers the vector      Exercise 8.1 :The matrix Eigenvalue problem.
