Another book from Arihant Publishers is the Plane Trigonometry Part-1 by S.L Loney. This book has been produced with care and expertise of the experts at the Arihant Publishing office. The book is targeted towards aspiring and energetic students who are appearing for AIEEE and other competitive engineering examinations. The theory part of syllabus has been explained point wise in between each chapter which reduces the time spent on learning and also helps in last minute revision. Every topic has been covered with abundant number of problems and their solutions. At the end of every chapter, there are enough number of objective and subjective type questions that will help the students get better idea of the topics. To help the students, at the end of the book, there are Logarithm tables, Natural Sines table, Natural Tangents table, Logarithmic Sines table, Logarithimic Tangents table and Radian Measure of Angles table.
The book covers the following topics:Measurement of angles, trigonometrical ratios for angles less than a right angle, simple problems in heights and distances, applications of algebraic signs to trigonometry, trigonometrical ratios of angles of any size, general expressions for all angles having a given trigonometrical ratio, trigonometrical ratios of the sum and difference of two angles, trigonometrical ratios of multiple and submultiple of angles, identities and trigonometrical equations, logarithms, The Principle of Proportional Parts, relations between the side and trigonometrical ratios of the angles of a triangle, solution of triangles, heights and distances, properties of a triangle, quadrilaterals, trigonometrical ratios, inverse circular functions, summation of some simple trigonometrical series, elimination and projections.
S.L Loney, the author of this book, has written other such student friendly books. The Elements of Coordinate Geometry and Elements of Statics and Dynamics are two of his other books.
The paperback edition of Plane Trigonometry Part-1 is available online with the ISBN-10 number of 9350943735 and ISBN-13 number of 978-9350943731.
