Introduction
The Council of Higher Secondary Education (CHSE), Odisha prescribes the official Mathematics textbooks for Higher Secondary Plus Two (+2) 1st Year (Class 11) and 2nd Year (Class 12) Science students. Published by the Odisha State Bureau of Textbook Preparation and Production, these volumes cover the complete state board curriculum. Whether preparing for the annual Higher Secondary Board examinations or competitive engineering entrances, students can access and download all parts for free below.
Features of CHSE Odisha +2 Mathematics Books
- CHSE Curriculum Aligned: Developed strictly in accordance with the prescribed syllabus and examination marking pattern for +2 Science and Arts students.
- Graded Problem Hierarchy: Each chapter progresses from fundamental axioms and basic formulas to high-level multi-step problem sets.
- Step-by-Step Solved Proofs: Contains worked numerical illustrations, standard theorem derivations, and geometric constructions.
- Exhaustive Exercise Sets: Packed with multiple-choice questions (MCQs), very short answer (VSA) questions, and long analytical problems for thorough self-assessment.
Benefits for Higher Secondary Students
- Board Examination Readiness: Over 90% of CHSE board theory and objective questions are directly modeled on these official textbook exercises.
- Competitive Exam Foundation: Builds analytical reasoning and mathematical agility required for national-level engineering entrance exams like JEE Main, JEE Advanced, and OJEE.
- Zero-Cost Digital Access: Provides instant, free offline access in high-resolution PDF format on smartphones, tablets, and computers.

Exam Tips for CHSE Mathematics
- Write Stepwise Solutions: Board examiners award marks for each stage—formula identification, substitution, intermediate calculation, and final boxed answer with units.
- Master Standard Calculus Proofs: Frequently practice derivations for standard derivatives, integration by parts, properties of definite integrals, and differential equations.
- Vector & 3D Coordinate Geometry: Draw clean geometric diagrams for lines, planes, and vector projections to secure full marks in long-answer sections.
Subject Overview
Sets, Relations & Functions (1st Year)
Introduces set operations, Cartesian products, equivalence relations, domain-range mapping, trigonometric functions, compound angles, and inverse trigonometry.
Algebra & Coordinate Geometry (1st Year)
Covers principle of mathematical induction, complex numbers, quadratic equations, linear inequalities, permutations and combinations, binomial theorem, sequences, and conic sections (circles, parabola, ellipse, hyperbola).
Matrices, Determinants & Vectors (2nd Year)
Details matrix operations, adjoint and inverse, solving linear systems via Cramer's rule/matrix method, vector scalar/cross products, and three-dimensional coordinate lines and planes.
Calculus (Differential & Integral) (2nd Year)
Explores limits, continuity, differentiability, Mean Value Theorems, maxima-minima, indefinite and definite integrals, area under curves, and first-order differential equations.
Probability & Linear Programming (2nd Year)
Covers conditional probability, Bayes' theorem, probability distributions, Bernoulli trials, and graphical solutions for linear programming optimization problems (LPP).
Important Chapters & High-Weightage Topics
- Integral Calculus: Definite Integrals (properties), Integration by Parts, and Area bounded by Curves.
- Differential Calculus: Continuity and Differentiability, Chain Rule, and Application of Derivatives (Tangents, Normals, Maxima & Minima).
- Vectors & 3D Geometry: Shortest Distance between Two Skew Lines, Equation of a Plane, and Scalar Triple Product.
- Matrices & Determinants: Finding Inverse of a Matrix and solving system of linear equations using Matrix Inversion Method.
- Relations & Functions: Types of Relations (Equivalence), One-One and Onto Functions, and Inverse Trigonometric Functions.
Study Strategy
- Daily Practice Routine: Dedicate at least 90 minutes every day to solving mathematical problems by hand rather than just reading through proofs.
- Formula & Identity Notebook: Maintain a personal formula sheet for trigonometric identities, standard differentiation/integration forms, and coordinate formulas.
- Time-Bound Sample Paper Solving: Practice solving past 5 years' CHSE board question papers within the official 3-hour limit to master time management.
Conclusion
The CHSE Odisha Plus Two Science Mathematics textbooks (Part 1 & Part 2 for both 1st and 2nd Year) serve as the essential cornerstone for achieving top marks in higher secondary board exams and national engineering entrances. Downloading these official, free PDF textbooks guarantees that students have standard, board-approved study material for daily practice and academic success.
