Differentials and Geographical Maps (UMAP)

Author: Yves Nievergelt


This module seeks to: 1) strengthen the students' intuition in multidimensional geometry; 2) consolidate their command of differentials; and 3) show important applications that rarely appear in calculus texts. It shows how to use differentials to determine whether a geographical map preserves angles, areas, or neither, and how to draw a loxodrome (a path along which the azimuth remains constant) between any two points on the surface of the Earth. The exercises are at a level intermediate between mechanical problems and abstract proofs and fit in any multivariable calculus course.
