Published by the National Council of Educational Research and Training, this textbook has been designed by subject experts to build strong conceptual foundations in algebra and pre-calculus topics. Every year, approximately 65-70% of CBSE board questions are directly sourced from NCERT textbooks, making this PDF an essential resource for scoring high marks.

Whether you are a student seeking convenient digital access, a teacher preparing classroom materials, or a parent supporting home study, the 12th Maths Book Volume 1 PDF English Medium download provides everything you need. The textbook follows a systematic approach—introducing concepts, demonstrating through worked examples, and reinforcing learning through graded exercises. Students preparing for boards alongside other subjects can also benefit from the CBSE 12th Physics Book Volume 1 for integrated science preparation.

12th Maths Book Volume 1 PDF English Medium Download – Complete Overview

The NCERT Mathematics textbook for Class 12 is divided into two volumes to ensure comprehensive coverage of the extensive syllabus prescribed by CBSE. Volume 1 focuses on algebraic concepts that form the building blocks for advanced mathematics, while Volume 2 covers calculus, vectors, and applied mathematics. Understanding this division helps students plan their study schedule effectively throughout the academic year.

The 12th Maths Book Volume 1 PDF is available in English medium and Hindi medium versions. The English medium edition is preferred by students appearing for competitive examinations, as most entrance tests like JEE, BITSAT, and VITEEE use English terminology. The PDF format allows students to study on smartphones, tablets, and computers without carrying physical books—particularly useful for revision during travel or between classes.

Each chapter in Volume 1 begins with an introduction connecting the topic to real-world applications, followed by definitions, theorems with proofs, solved examples, and exercise problems. The miscellaneous exercises at the end of each chapter contain higher-order thinking skill (HOTS) questions that frequently appear in board examinations. For comprehensive mathematics preparation, you may also refer to the CBSE 12th Maths Book Pdf English which covers both volumes.

Chapter-Wise Breakdown of Volume 1 Mathematics

Understanding the structure and content of each chapter helps students allocate study time effectively and identify high-weightage topics for focused preparation. Below is a detailed analysis of all four chapters included in the 12th Maths Book Volume 1 PDF English Medium download.

Chapter 1: Relations and Functions

This chapter builds upon the concepts introduced in Class 11 and explores advanced properties of relations including reflexive, symmetric, transitive, and equivalence relations. Students learn to identify and prove these properties through worked examples. The chapter also covers types of functions—one-one (injective), onto (surjective), and bijective functions—with their graphical representations.

The chapter includes topics on composition of functions and invertible functions. Students must understand that (fog)(x) ≠ (gof)(x) in general—a common mistake in board examinations. The miscellaneous exercise contains problems combining all concepts, which are frequently asked as 4-mark questions.

Chapter 2: Inverse Trigonometric Functions

Inverse trigonometric functions are essential for solving integration problems in Volume 2 and appear extensively in JEE Mathematics. This chapter defines principal value branches for sin⁻¹, cos⁻¹, tan⁻¹, cot⁻¹, sec⁻¹, and cosec⁻¹ functions. Students must memorise the domains and ranges of these functions, as direct questions worth 1-2 marks appear in every board examination.

The chapter covers properties of inverse trigonometric functions including sum and difference formulas. For example, tan⁻¹x + tan⁻¹y = tan⁻¹[(x+y)/(1-xy)] when xy < 1. Proof-based questions from this chapter carry 4-6 marks in board examinations. Students struggling with trigonometry fundamentals should revisit Class 10 concepts available in the CBSE 10th Maths Guide English Medium.

Chapter 3: Matrices

Matrices form one of the most scoring chapters in CBSE Class 12 Mathematics, contributing approximately 5-6 marks directly in board examinations. The chapter introduces matrix notation, types of matrices (row, column, square, diagonal, scalar, identity, zero matrices), and fundamental operations including addition, subtraction, and scalar multiplication.

Matrix multiplication follows the row-column method where the number of columns in the first matrix must equal the number of rows in the second matrix. Students must practise multiplication extensively as computational errors are common. The chapter also covers transpose of a matrix, symmetric and skew-symmetric matrices, and elementary row and column operations.

Chapter 4: Determinants

Determinants carry the highest weightage among Volume 1 chapters, with questions worth 6-8 marks appearing regularly in board examinations. The chapter begins with determinants of 2×2 and 3×3 matrices, followed by properties that simplify calculations. Understanding these properties—such as row/column operations, factor extraction, and the effect of interchanging rows—dramatically reduces computation time.

The chapter covers cofactors, adjoint of a matrix, and matrix inverse using the formula A⁻¹ = (1/|A|) × adj(A). This method is essential for solving systems of linear equations. The area of a triangle using determinants and Cramer’s Rule for solving simultaneous equations are frequently tested application problems.

Strategic Study Plan for Volume 1 Mathematics

Effective preparation requires understanding topic difficulty levels and allocating time accordingly. Based on analysis of previous years’ board papers and student performance data, the following study strategy optimises your preparation for the 12th Maths Book Volume 1 PDF content.

Begin your preparation with Chapter 3 (Matrices) as it introduces notation and operations needed for Determinants. Many students make the mistake of studying chapters in textbook order, but Matrices provides essential prerequisites for Chapter 4. After mastering matrix operations, move to Determinants where you’ll apply these concepts to find inverses and solve equations.

For Relations and Functions, focus on proving properties rather than just identifying them. Board examiners award full marks only when proofs follow proper mathematical structure with clear “let” statements, logical steps, and conclusions. Practice writing complete proofs for reflexive, symmetric, and transitive properties using set notation.

Inverse Trigonometric Functions requires memorisation combined with problem-solving practice. Create a formula sheet with all principal value ranges, properties, and identities. Solve at least 50 problems from NCERT and NCERT Exemplar before attempting previous years’ questions. This chapter connects directly to integration techniques in Volume 2, making thorough preparation essential.
