Emphazing computation skills, ideas and problem solving, rather than mathematical theory, this text omits most derivations and proofs, except where significant. Each concept is illustrated with an example, followed by a parallel problem and solution. Over 4200 graded problems are included. 本文强调计算技能、思想和问题解决,而不是数学理论,省略了大多数推导和证明,除非有重要意义。每个概念都用一个例子来说明,然后是一个平行的问题和解决方案。包括4200多个分级问题。
