comment Breaking up long equations in TeXForm
There is no answer to this, since it is impossible to do what you want, without manual editing of the Latex code generated, and using various Latex packages and methods as needed such as breqn, mathtools and its splitfrac, or amsmath and split env, and many other modification to the generated code. This is a Latex issue and nothing that Mathematica can do about it. If you have Latex code as \frac{very very long line}{x} then there is nothing but manual edit that can break it, including manual splitting if needed. The answer to your question is: There is no solution to this within Mathematica

comment Display functions without dependence?
This rule does not work for all functions of the independent variable. For example a[t] Exp[t] gives a Exp[t]. But may be that is ok with the OP, just wanted to point it out just in case.

comment Fourier Series of “Split” Defined Function
@ErikVesterlund For that, you can simply convert it to real. Like this: FourierSeries[x, x, 2]; ExpToTrig[%] which gives 2 Sin[x] - Sin[2 x]

comment Issues with $MachineEpsilon
The wiki web page linked to above has an implementation for finding $\epsilon$ using many different languages, is it possible to show an implementation using Mathematica as well? May be then it can be added to the wiki page along with all the other languages?

comment Fourier Series of “Split” Defined Function
@ErikVesterlund there are different definitions for the integral used to obtain the Fourier coefficients. In signal processing vs. say control vs. pure math. Different books use different definitions. So, if you are trying to compare results with some book, you need to make sure the same definitions are used in your code, else you'd think M is making a mistake. The help explains all the main 4 definitions and how to change them using FourierParameters->

comment Filling only part of a plot
Do you have a function to use to show how to do it? You can start by looking at Filling

comment Fourier Series of “Split” Defined Function
Yes, there is a way. Do you have an example of a function to use to show you? For your second question: Assuming[Element[n, Integers], Simplify[Cos[n Pi]]] gives (-1)^n and Assuming[Element[n, Integers], Simplify[Sin[n Pi]]] gives 0

comment Is linear interpolation applicable here
@Dr.Java you ask what language did you use?, I am using Mathematica, or now known as Wolfram language. This is a programming language made by company called Wolfram research. They have student version, and also personal version and commerical version. see wolfram.com to buy a copy from the online store there.
