Preprint available for "Taylor's theorem with remainder: the elusive 'c' is not so elusive" (submitted to the College Mathematics Journal); "Visualizing the chain rule (for functions over R and C) and more" (accepted by the International Journal of Mathematical Education in Science and Technology March 2008; proofs not yet requested); "SO(3) in pictures: a good example of lots of things" (possibly to be submitted to the Journal of Online Mathematics). Work in progress includes work on a generalized secant method, on numerical differentiation via the Dirac delta function and numerical integration, on mathematical modeling of ecosystems, and on using random points to aid in plotting graphs of functions f: R2-->R.
