Originally published as a four-volume set, this book is a comprehensive, one-stop source of mathematical instruction. Geared primarily to people involved in electronics and other technical fields, this text offers a complete course that spans the entire spectrum of mathematical computation. The author attempts to provide readers with an encyclopedia of working methods, and promotes understanding by explaining how and why mathematical principles work. Step-by-step, illustrated instructions and alternative techniques are provided for solving problems in basic arithmetic, algebra, geometry, trigonometry, and calculus and special emphasis is placed on analytical issues in computer programming and the use of computers for calculation.
