About the AuthorĪn editorial team of highly skilled professionals at Arihant works to ensure that the students get access to the best and accurate content through our books. Also, Five-Figure Logarithmic and Trigonometrical Tables are covered at the end of the book. Various examples are also given at the end of the study of the chapters. At the end of each chapter, unsolved practice exercises have been provided to help the candidates revise the concepts discussed in the chapter.

Theoretical explanation of concepts is given in points at the beginning of each chapter. Measurement of Angles Sexgecimal and centesimal measurements Circular or radians, Measurements, Trigonometric ratios for angles less than right angles, Simple problems in heights and distances, Application of algebraic notations to trigonometry detecting changes in ratio, Trigonometric of angles of any shape and sign Ratios, Common expressions for all angles having a given trigonometric ratio, Trigonometric ratio product formulas of sum and difference of two angles, Trigonometric ratios of multiples and submultiples of angles, Identities and trigonometric equations, Logarithms, Tables of logarithms, Theory of proportional parts, Relationship between sides and trigonometric ratios of angles of a triangle, Solution of triangles, Two sides and included angles, Ambiguous case, Heights and distances, Properties of a triangle, Quadrilateral, Regular polygon, Inverse circular function, Sum of some simple trigonometric series, elimination and inference, each covers different concepts of plane trigonometry. The book is divided into 21 chapters i.e. The current book on Plane Trigonometry Part 1 emphasizes presenting a modern treatment of the various concepts of Plane Trigonometry.

These classic texts are designed to serve as primary textbooks that play a vital role in building concepts from the very beginning as in-depth knowledge of concepts is essential for students preparing for various entrance exams.

Plane Trigonometry by SL Loney – The ‘Classic Text Series’ is the only classic work of its kind that began as a bestseller and remains a bestseller to this day.
