In revising the second edition, the strengths of the prior editions were retained while reflecting the changes
in the study of trigonometry during the last ten years. This edition deletes the use of logarithms entirely,
increases the use of calculators, and changes from the column form of working identity problems to the
horizontal continuous equation form. Tables are still provided for finding trigonometric function values in 10-
minute intervals, tenth of a degree intervals, and hundredth of a radian intervals. The review of geometry is
still provided in an appendix.
The book is complete in itself and can be used equally well by those who are studying trigonometry for
the first time and those who are reviewing the fundamental principles and procedures of trigonometry.
Each chapter contains a summary of the necessary definitions and theorems followed by a solved set of
problems. These solved problems include the proofs of the theorems and the derivation of formulas. The
chapters end with a set of supplementary problems with their answers.
Triangle solution problems, trigonometric identities, and trigonometric equations require a knowledge of
elementary algebra. The problems have been carefully selected and their solutions have been spelled out in
detail and arranged to illustrate clearly the algebraic processes involved as well as the use of the basic
trigonometric relations. |

 Electronic Government: Design, Applications and ManagementThe concept of electronic government (eGov), sometimes electronic governance, is about to emerge from a practitioners’ concept to one that also attracts research. Conferences abound, and research scales up from individual researchers and projects to institutes, both those governed by industry, such as IBM’s Institute for Electronic... | | Lie Algebras: Theory and Algorithms, Volume 56 (North-Holland Mathematical Library)
The aim of the present work is two-fold. Firstly it aims at a giving an account of many existing algorithms for calculating with finite-dimensional Lie algebras. Secondly, the book provides an introduction into the theory of finite-dimensional Lie algebras. These two subject areas are intimately related. First of all, the algorithmic perspective... | | Financial Accounting: An Integrated Statements Approach
Duchac, Reeve, Warren provides an effective new approach to help accounting majors and business students learn and understand financial accounting. The text introduces an integrated financial statements framework that clearly illustrates the inter-relationships between the cash flow statement, income statement and the balance sheet. This... |
