Excerpt from Descriptive Geometry: With Numerous Problems and Practical ApplicationsBy having several modifications under each problem, blackboard work can be readily assigned to the members of a class in recita tion, and no two students need be given exactly the same work.If the student is required to be prepared to make the con struction for each problem under all possible conditions, a thor ough understanding of the problem is necessary.A large number of carefully arranged problems and some practical applications are given.The first few problems on the point, line, and plane are fully analyzed. Then follows a list of problems left to the student for solution. In the part of the book devoted to curves and curved surfaces, more problems are analyzed and fewer are left to the student to solve without assistance.The importance of the study of Descriptive Geometry, both for mental discipline and on account of its industrial utility, is very ably set forth in two quotations that are given at the end of the introductory chapter.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
