Complete Trigonometry for CBSE and ISC Classes 11-12: Trigonometric Functions, Identities, Equations and Inverse Trigonometric Functions with Solved Examples, Exercises and Complete Solutions

The book develops the subject from first principles in seven chapters: Measurement of Angles, Trigonometric Functions, Conditional Identities, Trigonometric Equations, Solution of Triangles, Graphs of Trigonometric Functions and Inverse Trigonometric Functions. Each chapter builds the theory through clear definitions, theorems with complete proofs and solved examples of every type, so that students learn not only how to solve a problem but why each step works.

Practice lies at the heart of the book. Graded exercises lead from routine questions to challenging HOTS problems, and every chapter contains 100 multiple-choice questions, including assertion-reason questions of the kind now set in board examinations-700 MCQs in all. Answers, hints and complete solutions are given at the end of each chapter, while key-result boxes and Points to Remember make revision quick and effective.

Accurate diagrams and precisely plotted graphs support every topic, and every identity and answer has been carefully checked.

Clear, complete and exam-focused, the book suits classroom teaching, self-study and revision alike, and gives students a strong foundation for higher studies in mathematics, physics and engineering.
