Hello! I'm Jim Hefferon, from the Department of Mathematics and Statistics at St Michael's College and the University of Vermont. This is where I keep stuff related to Mathematics, including the undergraduate texts that I have written, along with ancillaries such as answers to exercises and classroom slides.
Also here are things for computing, cello, jogging, and ham radio.
The material here is all Freely available. The LaTeX sources for the texts and many other things are in my git repository.
