Introduction : 
  The concepts of gradient, divergence, and curl are of fundamental importance in vector calculus and frequently applied in vector fields.
Gradient is used to transform the scalar function to vector function. Then, the Gradient is a vector quantity. 

 Divergence is used to check the type of fluid that flows in a given point in a given area. It converts vector function to scalar function. Thus, it is a scalar quantity.

Curl of the vector field is used to find the rotational property of the rigid body about a fixed axis. It converts vector function to vector function. So , curl is a vector quantity.

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.

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.  Introduction,Fourier series expansion,fouriers theorem, functions of period 2π, Even and odd functions, linearity property, Exercise:7.2.6: https://drive.google.com/file/d/1_vW1OrF8lmOSq4F5Jq3zanDjtkbdZM6Q/view?usp=drivesdk ( pdf format material ).
