Geometry With Trigonometry

This book addresses a neglected mathematical area where basic geometry underpins undergraduate and graduate courses. Its interdisciplinary portfolio of applications includes computational geometry, differential geometry, mathematical modelling, computer science, computer-aided design of systems in mechanical, structural and other engineering, and architecture. Professor Barry, from his long experience of teaching and research, here delivers a modern and coherent exposition of this subject area for varying levels in mathematics, applied mathematics, engineering mathematics and other areas of application. Euclidean geometry is neglected in university courses or scattered over a number of them. This text emphasises a systematic and complete build-up of material, moving from pure geometrical reasoning aided by algebra to a blend of analytic geometry and vector methods with trigonometry, always with a view to efficiency. The text starts with a selection of material from the essentials of Euclidean geometry at A level, and ends with an introduction to trigonometric functions in calculus. Very many geometric diagrams are provided for a clear understanding of the text, with abundant Problem Exercises for each chapter. Students, researchers and industrial practitioners would benefit from this sustained mathematisation of shapes and magnitude from the real world of science which can raise and help their mathematical awareness and ability

"A fascinating book that reminded me of a time when geometry played a more central and cohesive role. Primarily for post A-level students, it should be considered for the library shelves of mathematics departments where ‘old style geometry is still appreciated and enjoyed." - Mathematics Teaching

"Geometrical thinking is still very much alive. Dr Barry s pragmatic approach in a combination of Euclidean treatment of geometry is pitched at university degree level. Students who take trouble to become familiar with the tools introduced will find the spirit of geometry logically unfolded in a fascinating challenge." - The Mathematical Gazette"A fascinating book that reminded me of a time when geometry played a more central and cohesive role.

Addresses a neglected mathematical area of which geometry and trigonometry form an important core component, as they underpin analysis in its manifold aspects and applications in classical applied mathematics and sundry types of science and engineering. In collaboration with the National Council for Curriculum and Assessment in Ireland, this book has formed the basis of a new syllabus due to be adopted for the teaching of geometry for the second level cycle.
