This is the only text that introduces differential geometry by combining the following: an intuitive geometric foundation, a rigorous connection with the standard formalisms, computer exercises with Maple, and a problems-based approach. Has running theme on the intrinsic/extrinsic view of curves and surfaces. *Uses basic intuitive geometry as a starting point which makes the material more accessible and the formalism more meaningful. *Topics are based on and introduced through 55 core problems. *The ribbon test for geometrically finding geodesics is introduced in Chapter 1. Then it is proven that it works in Chapter 3. Finally, using ruled surfaces in Chapter 7, it is proven that almost all geodesics can be found this way. *Introduces hyperbolic geometry in the first chapter. *Supports an intuitive grasp of concepts. *Includes 19 computer projects for use with Maple. *An Instructor's Manual with complete solutions for each problem is available.
