### Methods of Mathematical Physics

DESCRIPTION & OBJECTIVES

This course provides a wide range of analytical mathematical techniques essential to the solution of advanced problems in physics. The main objective is to develop intuition towards formulating physical phenomena in mathematical language and gain an appreciation of the analytical methods that are most commonly used to solve problems in physics. This course has an in-depth understanding of the basics of mathematics.
