I'm using TexStudio and I would like to know how to increase the distance between the Table of Content part of my document and the first section.

    \begin{document}
\maketitle
\tableofcontents
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\section{Faktorregel}


I tried different ways of placing \\[2cm] but it didnt worked, also the other questions regarding spacing \tableofcontent all relate to spacing within the Table of Contents.

You can insert vertical space using \vspace{<len>} where you specify <len> in any appropriate dimension (or dimensions expression). For example, to insert a space of 5 typical lines, use
\tableofcontents

There is also a starred version \vspace*, but that it typically used if you wish to force space that starts at the top of the page. Also, \addvspace{<len>} may be worth using, adding vertical space only up to <len>.
