Main Author: Mason, John
Format: electronic Article
Item Description:This column will publish short (from just a few paragraphs to ten or so pages), lively and intriguing computer-related mathematics vignettes. These vignettes or snapshots should illustrate ways in which computer environments have transformed the practice of mathematics or mathematics pedagogy. They could also include puzzles or brain-teasers involving the use of computers or computational theory. Snapshots are subject to peer review. In this snapshot, John Mason alternates between a traditional mathematical treatment of a geometry problem about the tangent to a cubic polynomial and an exploration of it with dynamic geometry software. With each alternation, we get a more generalized view of the problem, losing the tangents and the cubics along the way.
