études

This is an index of études, or short problems, used to practice and hone particular skills.

In particular, this repository grew out of a desire to separate out non-coursework from the agony archive (which contains course-related problems and study material from myself and my classmates) and put all the random quasiacademic sidequesting in one place. LaTeX files are compiled with the agony class.
