The content published here comes from various sources, including past exams, homework assignments and notes from university classes I attended. Although I have rewritten most of the material myself, some examples or practical problems may have been reproduced verbatim from books or other resources I used, as I failed to keep track of their origin over the course of the years.

If you believe that any of the content published here infringes your copyright and would like it removed, please feel free to contact me. I will do my best to review and possibly replace the material in question.
