There is no particular textbook for the course. Some useful references listed below.

• Advanced Engineering Mathematics, Erwin Kreyszig, Wiley
• Advanced Engineering Mathematics, Peter V. O'Neil, WadsWorth
• Mathematical Methods for Physicists, 6th Edition, George B. Arfken, Hans J. Weber, Frank Harris, Academic Press. 7th Edition is available online at ScienceDirect through the library's subscription. 5th Edition hardcopy is available for check-out at the Gulfcoast campus library.

We study some important differential equations that arise in physics and special functions as their solutions. We also discuss some physical applications of special functions. Those special functions include Bessel functions, Legendre functions, Hermite functions, Laguerre functions, Chebyshev polynomials, hypergeometric functions.

Tuesday/Thursday 1:00-2:15pm in SH 309

No tests. The final grade for the course is based on cummutative grades from homework assignments and in-class presentations.

$your-LaTex-code-here$

If you want to try Latex in your Windows computer, you may download it for free from MikTex Project Page. If you are using a Linux distribution, usually Latex is a part of the standard packages repository. (The package is called texlive.) To use Latex, you need an editor. Texmaker is a nice interface for using Latex. You can edit/compile/view all together in Texmaker. If you don't want to deal with commands, there is a WYSWYG (What You See is What You Get) interface for Latex called Lyx.

In our course we also need to use a mathematics software package for certain computations. We don't have licenses of commercial mathematics software packages such as Maple or Mathematica to use for class, so I have decided to use Maxima which is an open source mathematics software package. The syntax is similar to Mathematica, so those who are familiar with Mathematica can easily adapt to the use of Maxima. To download and install Maxima in your personal computer, go to Maxima Donwload page. Windows and MacOS users will find download files that are suitable for their OS platforms. If you are using Linux distros such as CentOS or Fedora, try to use rpm files available from Maxima download page. Another place you may download Maxima rpm files is here. If you are using Ubuntu, it is really easy to install since Maxima is a part of the standard repository. You can use "Synaptic" to install Maxima or just open a terminal, type "sudo apt-get install maxima" ("sudo apt-get install xmaxima" if you want GUI version) without " " and press enter.
