• Personal Information

• For your entertainment and enlightenment

These papers were written over a number of years for my own entertainment, except for the last, "Advanced Multivariable Calculus." It was written at USU as notes for the students in my advanced calculus classes. It is more of an outline, with no proofs or examples. They were presented in class.

So, if you read any of them and want to comment, contact me by EMAIL
