RetroCraft / etudes

Math and programming études from various sources

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.
