A TEXT BOOK OF TRIGONOMETRY PROBLEMS & SOLUTIONS

This book on TRIGONOMETRY has been specially written for the students of Science and Engineering. The basic purpose of the book is to provide the subject matter in a simple and lucid way so that the students could find no difficulty in understanding it. In terms of content, it covers the following chapters: Complex Numbers, Exponential Trigonometric and Hyperbolic Function of a Complex Variable (Separation into Real and Imaginary Parts), Logarithms of Complex Numbers, Inverse Circular and Hyperbolic Functions of Complex Numbers, Gregory Series, Trigonometrical Expansions and Summation of Trigonometrical Series. Each chapter of this book contains brief theory and fairly large number of examples and exercise. In selecting exercise variety has been the main consideration and it has been avoided to overload the book with too much drill work.

本《三角学》教材专为理工科学生编写。本书的核心宗旨是以浅显易懂的方式呈现学科内容，确保学生在学习过程中无理解障碍。就内容框架而言，本书涵盖以下章节：复数（Complex Numbers）、复变量的指数、三角函数与双曲函数（Exponential Trigonometric and Hyperbolic Function of a Complex Variable，含实部与虚部分离内容）、复数的对数、复数的反三角函数与反双曲函数、格雷戈里级数（Gregory Series）、三角展开式与三角级数求和（Trigonometrical Expansions and Summation of Trigonometrical Series）。本书每一章均包含精简的理论阐述，以及数量可观的例题与习题。在习题选编环节，本书以题型多样性为首要考量，避免因过多机械训练内容加重读者负担。
