Digital notes (LaTeX)
Searchable digital versions of the handwritten notes, typeset in LaTeX (the notes are written in Turkish). Template and build: latex-sablon.
Notice: The digital notes were created from the handwritten notes with the help of Claude (Anthropic); they are meant as a supplementary resource and may contain errors. Always rely on the original notes and the official course materials.
