Mathematical methods is an important branch of mathematics. The main objective of this course is to provide the students with a range of mathematical methods that are essential to the solution of advanced problems encountered in the fields of applied physics and engineering. In addition this course is intended to prepare the students with mathematical tools and techniques that are required in advanced courses offered in the applied physics and engineering programs

Learning Outcomes

The students would be able to understand the types of transformations and their practical use. Also, they would be able to know their importance in higher education in particular research.


  1. Fourier Methods: The Fourier transforms
  2. Fourier analysis of the generalized functions
  3. The Laplace transforms
  4. Hankel transforms for the solution of PDEs and their application to boundary value problems
  5. Green’s Functions and Transform Methods: Expansion for Green’s functions
  6. Transform methods. Closed form Green’s functions. Perturbation Techniques
  7. Perturbation methods for algebraic equations
  8. Perturbation methods for differential equations
  9. Variational Methods: Euler-Lagrange equations
  10. Integrand involving one, two, three and n variables
  11. Special cases of Euler-Lagrange’s equations
  12. Necessary conditions for existence of an extremum of a functional
  13. Constrained maxima and minima
