# Practical Problems in Mathematics for Electronic Technicians

Cengage Learning, 2004 - Education - 245 pages
Success in the electronics field requires a substantial background in mathematics. This updated book is written to provide beginning students with these needed skills. Practical, easy-to-understand problems help prepare students for the types of problems that professional electronic technicians face everyday. As part of the successful Practical Problems in Mathematics series, this fourth edition features expanded coverage of scientific notation, increased problems to be solved using a calculator, additional information on RLC circuits, and a new unit on simultaneous equations that includes coverage of Kirchoff's Law. Benefits: * trade-specific coverage develops an acute awareness of electronics symbols, basic circuits, and component terminology * a step-by-step approach to math concepts begins with basic arithmetic and progresses through algebra and trigonometry, helping students master each level of skill required by today's technicians * extensive multi-level word problems challenge students to use logical deduction, preparing them for situations like those to be encountered on the job * abundant example problems offer opportunities to practice math principles again and again * an Instructor's Guide is available to accompany the book
