### Mathematical Methods (MATH-304)

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.
