Technical Mathematics


Book Description

This textbook has been in constant use since 1980, and this edition represents the first major revision of this text since the second edition. It was time to select, make hard choices of material, polish, refine, and fill in where needed. Much has been rewritten to be even cleaner and clearer, new features have been introduced, and some peripheral topics have been removed. The authors continue to provide real-world, technical applications that promote intuitive reader learning. Numerous fully worked examples and boxed and numbered formulas give students the essential practice they need to learn mathematics. Computer projects are given when appropriate, including BASIC, spreadsheets, computer algebra systems, and computer-assisted drafting. The graphing calculator has been fully integrated and calculator screens are given to introduce computations. Everything the technical student may need is included, with the emphasis always on clarity and practical applications.




Algebra and Trigonometry


Book Description

Precalculus


Book Description

"Precalculus is intended for college-level precalculus students. Since precalculus courses vary from one institution to the next, we have attempted to meet the needs of as broad an audience as possible, including all of the content that might be covered in any particular course. The result is a comprehensive book that covers more ground than an instructor could likely cover in a typical one- or two-semester course; but instructors should find, almost without fail, that the topics they wish to include in their syllabus are covered in the text. Many chapters of OpenStax College Precalculus are suitable for other freshman and sophomore math courses such as College Algebra and Trigonometry; however, instructors of those courses might need to supplement or adjust the material. OpenStax will also be releasing College Algebra and Algebra and trigonometry titles tailored to the particular scope, sequence, and pedagogy of those courses."--Preface.

The Fourth Side of the Triangle


Book Description

A fashion designer’s murder draws legendary sleuth Ellery Queen into a New York society family’s tangled web of secrets. Ever since New York was Nieuw Amsterdam, the McKells have been building their fortune. Combining Scottish thrift with American know-how, they built an empire that, by the 1930s, stretched across the globe. No one in the family found more success than Ashton McKell, an entrepreneur who counts his wealth in the hundreds of millions, who smokes twenty cigars a day, and whose only problem is his son Dane, an adventurous soul who shocks his father by giving up business for the disgraceful pursuit of writing. Despite their differences, Dane loves his father. He is shocked when he learns the old man is having an affair—and thunderstruck when Ashton is accused of murder. When his father’s mistress is found dead, Dane will do anything to free Ashton. And no detective is more suited to this puzzling case of blackmail, lust, and greed than the singular Ellery Queen.
