Course Description

This course is intended to provide a brief, but solid, modern introduction to various basic geometries using analytic methods. For this term, this course will concentrate on various plane geometries related to the so-called "non-Euclidean" geometries with emphasis on hyperbolic plane geometry. A brief introduction to Solid Euclidean and Hyperbolic geometries using quaternion will also be included.
