The Use of Continued Fractions in Botany (UMAP)

Author: Jean, Roger V.


Students will 1) become acquainted with some of the most interseting aspects of continued fractions; 2) realize and appreciate the role of some mathematical concepts in botany; 3) develop observational capacities in the surrounding nature; and 4) acquire the fundamental notions that will eventaully allow them to investiagte an important field of research in biomathematics.
