# Mathematical Methods in Physics 1

This course may be unavailable.

### Overview

This would be the first of a two-part series on Mathematical Methods in Physics. The aim here is to provide a solid mathematical foundation for the budding Physicist eager to climb the ladder of self-learning. This course is designed to cater to an undergraduate student who excitedly embarks on a study of Physics, but is obstructed by the mathematics which appears so forbidding. The approach we will follow is one of showing many examples, and weaving the theory around examples. When possible, we will show how Mathematica can be used to offer extra insight. INTENDED AUDIENCE :NonePREREQUISITES : We try to make this self-contained. However, some familiarity with the basic mathematical tools used in say, the first courses on Mechanics, Electromagnetism, would help.INDUSTRIES SUPPORT :Quantitative Finance and Scientific consulting companies

• Hiyasmita Das
Good course but voice of the professor was not that clear, but it is understandable. The professor taught almost everything about Differential Equation.
