Hi all-
I have just posted a short paper on the Los Alamos e-print
archives that may be of interest to some of you:
math.GM/0010065 [abs, src, ps, other] :
Title: Introductory Calculus from the Viewpoint of Non-Standard
Analysis - Derivative of Sine and
Cosine
Authors: Jack L. Uretsky
Comments: LaTeX; 19 pp, 6 figs
Subj-class: General Mathematics
MSC-class: 00-01; 97-01
This article exemplifies a novel approach to the teaching of
introductory differential calculus using
the modern notion of ``infinitesimal'' as opposed to the traditional
approach using the notion of
``limit''. I illustrate the power of the new approach with a
discussion of the derivatives of the sine
and cosine functions. (45kb)
