11th Maths Book: NCERT Class 11 Mathematics, Contents Inside

The 11th maths book for Class 11 is the NCERT Mathematics textbook, and this page links every one of its 14 chapters as an official PDF from ncert.nic.in. The book runs to 313 printed pages and 82 named sections, and the files below are NCERT’s own editions — free, current and ready to open.

This page also shows what is actually inside the book, which the PDF alone does not tell you: each chapter’s named sections, page spans and exercise counts, measured from the textbook itself. Ten of the fourteen chapters are flagged for review, so treat the counts as close approximations and the official PDF as the source of truth.

We indexed this listing from the official NCERT edition for the current academic session.

Class 11th Maths NCERT PDF: the book, measured

• 14 chapters, all with PDF links pointing to ncert.nic.in.
• 313 printed pages and 82 named NCERT sections across the whole book.
• 0 activities — this book prints no hands-on activities, so the solved examples inside each chapter are the worked practice and the end-of-chapter exercises are the test.
• Longest chapters by printed pages: Limits and Derivatives at 40 pages, Trigonometric Functions at 33, and Conic Sections and Statistics at 32 each.
• 10 of 14 chapters are flagged for review, so the directory counts below are approximations; the official PDF is the source of truth.
• Each chapter’s study-page status on this site (Available, Drafting, or Not yet built) is rendered in the chapter-names section below.

What each chapter actually contains

The directory below renders per-chapter counts. A section is one of NCERT’s own numbered headings; a question is an end-of-chapter exercise; an activity is a hands-on task printed in the book, and this book has none. The book prints no numbered figure captions, so there is no figure index on this page.

Chapter 1: Sets (23 pages)

Sets give Class 11 its foundation: a set is a well-defined collection of objects, which means you can always tell whether a given object belongs to it.

The chapter moves from the empty set through finite, infinite and equal sets to subsets, then introduces Venn diagrams and the operations on sets — union, intersection, difference and complement — that later chapters use almost without naming them.

1. Sets and their Representations
2. The Empty Set
3. Finite and Infinite Sets
4. Equal Sets
5. Subsets
6. Subsets of set of real numbers
7. Universal Set
8. Venn Diagrams
9. Operations on Sets
10. Complement of a Set

With 11 named sections and 39 exercise questions, Sets is the language the rest of the book runs on — Chapter 14’s probability builds directly on its set operations.

Chapter 2: Relations and Functions (19 pages)

Relations and Functions is where the book turns pairs into structure: an ordered pair keeps two objects in a fixed order, the Cartesian product builds pairs from two sets, and a relation is a subset of that product.

A function is the special relation that assigns exactly one output to each input, and the chapter closes by graphing the standard functions whose shapes later chapters refer to.

1. Cartesian Products of Sets
2. Relations
3. Functions
4. Some functions and their graphs

5 named sections and 28 exercise questions; the function idea here is what Chapter 12’s calculus assumes.

Chapter 3: Trigonometric Functions (33 pages)

Trigonometry in Class 11 starts from angles measured in radians, with the arc-length relation \( l = r\theta \) and the conversion formulas between degree and radian measure. From there the chapter defines the trigonometric functions, fixes their signs quadrant by quadrant, records their domain and range, and finishes with the sum-and-difference formulas for two angles.

1. Angles
2. Relation between radian and real numbers
3. Relation between degree and radian
4. Trigonometric Functions
5. Sign of trigonometric functions
6. Domain and range of trigonometric functions
7. Trigonometric Functions of Sum and Difference of Two Angles

8 named sections and 42 exercise questions across 33 pages make it one of the longest chapters in the book.

Chapter 4: Complex Numbers and Quadratic Equations (13 pages)

A complex number is written \( a + ib \), with real part \( a \) and imaginary part \( b \); this chapter builds the algebra of adding, multiplying and dividing them, then defines the modulus and the conjugate. The Argand plane gives complex numbers a geometric home, and polar representation expresses them by distance from the origin and angle.

1. Complex Numbers
2. Algebra of Complex Numbers
3. The Modulus and the Conjugate of a Complex Number
4. Argand Plane and Polar Representation

The directory lists 6 named sections here, and only 1 question — because the exercise extraction for this chapter is incomplete. Use the official PDF above for this chapter’s full exercise set; the count shown is not the real total.

Chapter 5: Linear Inequalities (pp. 89–99)

A linear inequality relates two expressions by one of the symbols \( \lt, \gt, \le, \ge \). The rules are close to equation solving: equal numbers may be added to or subtracted from both sides, and both sides may be multiplied or divided by a positive number. The chapter then shows the graphical representation of solutions in one variable.

1. Inequalities (p. 89)
2. Algebraic Solutions of Linear Inequalities in One Variable and their Graphical Representation (p. 91)

3 named sections and 26 exercise questions; it is the first place in the book where an algebraic condition is read back from a graph.

Chapter 6: Permutations and Combinations (26 pages)

Counting in Class 11 rests on the fundamental principle: if one event can occur in \( m \) ways and a following event in \( n \) ways, the pair can occur in \( m \times n \) ways. Permutations count ordered arrangements, combinations count unordered selections, and the derivations of \( ^nP_r \) and \( ^nC_r \) are the chapter’s core results.

1. Fundamental Principle of Counting
2. Permutations
3. Permutations when all the objects are distinct
4. Derivation of the formula for \( ^nP_r \)
5. Combinations

6 named sections and 31 exercise questions; Chapter 7’s binomial coefficients are the \( ^nC_r \) introduced here.

Chapter 7: Binomial Theorem (9 pages)

The binomial theorem expands \( (a + b)^n \) for any positive integer \( n \) as a sum of terms whose coefficients are \( ^nC_r \). The chapter states the theorem for positive integral indices, then works through special cases of the expansion that make the pattern simpler to apply.

1. Binomial Theorem for Positive Integral Indices
2. Binomial theorem for any positive integer \( n \)
3. Some special cases in the expansion of \( (a + b)^n \)

4 named sections and 7 exercise questions; at 9 pages it is the shortest chapter in the book, and it depends directly on Chapter 6’s combinations.

Chapter 8: Sequences and Series (16 pages)

A sequence lists numbers in a definite order according to a rule; a series is what you get when you add the terms of a sequence. The chapter studies geometric progressions, defines the geometric mean of two positive numbers, and records the relationship between the arithmetic mean and the geometric mean.

1. Sequences
2. Series
3. Geometric Progression (G. P.)
4. Geometric Mean (G.M.)
5. Relationship Between A.M. and G.M.

6 named sections and 45 exercise questions — one of the heavier exercise loads in the book.

Chapter 9: Straight Lines (25 pages)

Straight Lines returns to coordinate geometry with one central definition: the slope \( m \) of a non-vertical line through \( (x_1, y_1) \) and \( (x_2, y_2) \) is \( m = \frac{y_2 – y_1}{x_2 – x_1} \). The chapter then develops the various forms of the equation of a line and finishes with the distance of a point from a line.

1. Slope of a Line
2. Slope of a line when coordinates of any two points on the line are given
3. Various Forms of the Equation of a Line
4. Distance of a Point From a Line

5 named sections and 47 exercise questions; together with Chapter 10, it extends the coordinate geometry begun in Class 10.

Chapter 10: Conic Sections (32 pages)

Conic Sections takes the plane sections of a double cone — circle, parabola, ellipse and hyperbola — and reduces each to a standard equation. A circle is the set of all points equidistant from a fixed point; the conics each come with their standard equations, eccentricity and latus rectum.

1. Sections of a Cone
2. Degenerated conic sections
3. Circle
4. Parabola
5. Standard equations of parabola
6. Latus rectum
7. Ellipse
8. Latus rectum
9. Hyperbola
10. Eccentricity
11. Latus rectum

12 named sections — the highest section count in the book — and 49 exercise questions across 32 pages.

Chapter 11: Introduction to Three Dimensional Geometry (9 pages)

Three-dimensional geometry starts by setting up three mutually perpendicular coordinate axes and the coordinate planes they determine. A point in space gets three coordinates, and the chapter’s main result is the distance formula between two points in space.

1. Coordinate Axes and Coordinate Planes in Three Dimensional Space
2. Coordinates of a Point in Space
3. Distance between Two Points

4 named sections and 9 exercise questions; it is a short chapter whose working core is that three-dimensional distance formula.

Chapter 12: Limits and Derivatives (pp. 217–256)

Calculus begins here, and the book chooses an intuitive route: it introduces the idea of a derivative first, then formalises limits, then studies limits of trigonometric functions, and finally returns to derivatives and their algebraic rules.

1. Intuitive Idea of Derivatives (p. 217)
2. Limits (p. 220)
3. Limits of Trigonometric Functions (p. 234)
4. Derivatives (p. 239)

5 named sections and 29 exercise questions; at 40 pages it is the longest chapter in the book and the entry point to calculus.

Chapter 13: Statistics (pp. 257–288)

Statistics measures how spread out data is, through measures of dispersion. The chapter defines range as the maximum value minus the minimum value, then develops mean deviation, variance and standard deviation for ungrouped and grouped data.

1. Measures of Dispersion (p. 259)
2. Range (p. 259)
3. Mean Deviation (p. 259)
4. Variance and Standard Deviation (p. 271)

5 named sections and 16 exercise questions.

Chapter 14: Probability (pp. 289–313)

Probability closes the book with an axiomatic approach: an event is a subset of the sample space, and the empty set is the impossible event. Probabilities are assigned to events through axioms, and the chapter applies them to random experiments.

1. Event (p. 289)
2. Axiomatic Approach to Probability (p. 295)

2 named sections and 28 exercise questions; the closing chapter is built on the set language of Chapter 1.

Class 11 maths all chapter names, and the study page for each

The block below lists all 14 chapter names in order and shows the state of each chapter’s dedicated study page on this site, where one exists.

How to use the CBSE Class 11 Maths textbook

Work through the book in this order, and each block prepares the next.

1. Start with Chapters 1–2 — the set language and function idea that everything else assumes.
2. Do Chapter 3 next: 33 pages of trigonometry that reappear in limits and in Class 12.
3. Work Chapters 4–8 as one algebra block: complex numbers, inequalities, counting, binomial theorem and sequences.
4. Then the coordinate geometry block, Chapters 9–11, continuing from Class 10.
5. Chapter 12 is the shift into calculus — move slowly through its solved examples.
6. Finish with Chapters 13–14, statistics and probability, which reuse earlier material.
