Here I show some of the drawings I've done in Latex, using mainly the Tikz package. The code is overall simple, and the pictures are placed in 6 different cattegories, according to their theme:
1 - free body diagrams;
2 - geometry constructions;
3 - graphs (of functions);
4 - logical circuits;
5 - diagrams on the complex plane;
6 - other.
The file MyTikz.tex is an all-in-one tex file holding the code for every picture, and its compilation results in the MyTikz.pdf. The .tex file is commented so that, should you be insterested in one of my drawings, you can simply open it and harvest the image of interest's source code.
Take a look at a couple of my favorites:
