 \section{Simple equations on text}
 \label{sec:eq-text}

 Here you can see simple equations along with text $x$, $y$ and \(z\) are in math mode. This mode is known as \textbf{inline} mode and it is recommended to write short equations like: $-10 \leq x \leq 10$. Thus, if complex and long equations are required, it is recommended to use the equation environment.\par

 \section{Equation environment}
 \label{sec:environment}

 Here we can find a way to write long equations like \eqref{eq:fraction}:
 \begin{equation}
  \label{eq:fraction}
  f(t)=\sqrt{\frac{t-a}{t+a}}
 \end{equation}
 \noindent here $t$ is time in seconds.

 More complex equations can be written using symbols and commands from math-mode. An example is the Fourier coefficients equations \eqref{eq:a0},\eqref{eq:an} and \eqref{eq:bn}:
 \begin{eqnarray}
  a_0=\frac{1}{T}\int_0^T f(t)dt  \label{eq:a0}\\
  a_n=\frac{2}{T}\int_0^T f(t)\cdot \cos{\left(\frac{2\pi nt}{T}\right)}dt  \label{eq:an}\\
  b_n=\frac{2}{T}\int_0^T f(t)\cdot \sin{\left(\frac{2\pi nt}{T}\right)}dt  \label{eq:bn}
 \end{eqnarray}

 Previous equations are used to define the Fourier series as:
 \begin{equation}
  \label{eq:fourier}
  g(t)=a_0+\sum_{m=1}^{\infty}a_m \cos{\left(\frac{2\pi mt}{T}\right)}++\sum_{m=1}^{\infty}b_n \sin{\left(\frac{2\pi nt}{T}\right)}
 \end{equation}

  #### Font sizes
  The font formats and sizes **are not modified frequently**, most of the time LaTeX makes a good work with them. However, here are some common font size modifiers to work with:

  |Class option|10pt |11pt|12pt|

  If you need an extended manual please take a look to the [short math guide](http://gmarxcc.com/fourier/short-math-guide.pdf).

  #### Matrices 

  By using the `amsmath` package it is possible to write easily matrices by:

  ``` tex
  \begin{bmatrix}
    1 & 2 & 3\\
    a & b & c
  \end{bmatrix}
  ```

  you also use `pmatrix`, `Bmatrix` , `vmatrix`, and  `Vmatrix`.
