  • Comprehensive coverage of concepts dealing with finding angles and sides of triangles
  • Giving extensive self-sufficient problems to help students master trigonometry
  • Worked examples and exercises conform to metric system.


This book on trigonometry is the product of the author?s experience in teachinglearning the subject. His realization for a textbook on trigonometry that explains core concepts of triangles dealing with their sides and their angles made him to write this textbook. The discussion on various concepts and exercises given in it will provide encouragement to serious learners. It is a must-have book for those preparing for various science and engineering entrance examinations.


S L Loney, MA (1860–1939) was Professor of Mathematics at the Royal Holloway College, Egham Surrey, London, UK and a fellow of Sidney Sussex College, Cambridge, UK. Loney was educated at Maidstone Grammar School, in Tonbridge and at Sidney Sussex College, Cambridge, UK, where he graduated as 3rd Wrangler in 1882. He has authored numerous books on Mathematics which are widely in use. This book still happens to be the only reference book on the subject used across various universities.
