The geometric viewpoint. A survey of geometries

This survey textual content with a ancient emphasis helps a number of varied classes. It contains team tasks regarding using expertise or verbal/written responses. The textual content strives to construct either scholars' instinct and reasoning. it really is perfect for junior and senior point classes.

Geometry: Concepts and Applications, Student Edition

An awesome application for suffering studentsGeometry: recommendations and purposes covers all geometry ideas utilizing an off-the-cuff procedure.

The Geometry of Complex Domains

The geometry of advanced domain names is a topic with roots extending again greater than a century, to the uniformization theorem of Poincaré and Koebe and the ensuing evidence of life of canonical metrics for hyperbolic Riemann surfaces. nowa days, advancements in numerous complicated variables via Bergman, Hörmander, Andreotti-Vesentini, Kohn, Fefferman, and others have spread out new chances for the unification of complicated functionality conception and intricate geometry.

Calculus: Early Transcendental Functions

Now in its 4th version, Smith/Minton, Calculus: Early Transcendental capabilities bargains scholars and teachers a mathematically sound textual content, powerful workout units and chic presentation of calculus options. whilst packaged with ALEKS Prep for Calculus, the simplest remediation device out there, Smith/Minton bargains an entire package deal to make sure scholars luck in calculus.
