# Mathematical Methods of Physics

## Objectives

The objective of this course is the acquisition of proficiency in the aplication of mathematical methods to the solution of physical problems.

We will also use this course as an opportunity for students to learn how to use modern mathematical packages on computers to do calculations, graphing, and numerical simulations.
