Application of Derivatives Class 12 Maths NCERT Book: Problem Count and Exercise Distribution
The chapter notes address this in the same order as the NCERT textbook.
The current NCERT print packs 49 solved examples with five numbered exercises plus a Miscellaneous Exercise. The table below shows how the question blocks are distributed.
| Block | Type | Question Count | Primary Skill |
|---|---|---|---|
| Intext Solved Examples | Solved-out | 49 | Rate of change, tangents, monotonicity, maxima-minima |
| Exercise 6.1 | Practice | 18 | Rate of change of quantities |
| Exercise 6.2 | Practice | 19 | Increasing and decreasing functions |
| Exercise 6.3 | Practice | 27 | Maxima and minima; absolute extrema |
| Miscellaneous Exercise | Mixed | 18 | Mixed-concept proofs and optimisation |
Exercise 6.3 (Maxima and Minima) is the heaviest block. It supplies roughly 60 percent of every long-answer question CBSE has set from Application of Derivatives in the past five years, including the perennial open-box and cone-in-sphere classics.
2026-27 Rationalisation Note: What Changed in Class 12 Maths Chapter 6
The the PDF address this in the same order as the NCERT textbook.
The current edition merged the earlier Tangents-Normals and Approximations sections into the Maxima-Minima flow, and trimmed the Mean Value Theorem (Rolle's, Lagrange) sub-section. The kept content focuses on rate of change, monotonicity, and optimisation.
| Topic | Older NCERT | 2026-27 NCERT |
|---|---|---|
| Rate of change of quantities | Present | Kept |
| Increasing and decreasing functions | Present | Kept |
| Maxima and minima; closed-interval extrema | Present | Kept |
| Tangents and normals (dedicated section) | Present | Removed (concept retained inline; dedicated exercise dropped) |
| Approximations (dedicated section) | Present | Removed (concept retained in solved examples) |
| Mean Value Theorem (Rolle's, Lagrange) | Present | Removed |
The chapter now hinges on monotonicity intervals plus maxima-minima with the first- and second-derivative tests. Do not attempt CBSE 2016 to 2019 Rolle's-theorem proof questions, because those are no longer in the syllabus.

NCERT Section-by-Section Breakdown for Class 12 Maths Chapter 6
The this chapter address this in the same order as the NCERT textbook.
The current NCERT print runs six numbered sections plus a Miscellaneous Exercise and a Summary. The table maps each section to its central concept and exam relevance.
| Section | Title | Ends with | Skill Tested |
|---|---|---|---|
| 6.1 | Introduction | - | Motivation; what does $dy/dx$ measure? |
| 6.2 | Rate of Change of Quantities | Exercise 6.1 | Related rates via chain rule |
| 6.3 | Increasing and Decreasing Functions | Exercise 6.2 | Sign of $f'$; strict vs.\ non-strict monotonicity |
| 6.4 | Maxima and Minima | Part 1 (theory) | Local vs.\ absolute; critical points |
| 6.5 | Maximum and Minimum Values in a Closed Interval | Exercise 6.3 | Absolute extrema on $[a,b]$; first- and second-derivative tests |
| - | Miscellaneous Examples and Exercise | Miscellaneous Exercise | Optimisation classics: open box, cone, cylinder |
| - | Summary and Historical Note | - | Recap; Pierre de Fermat and the birth of optimisation |
Sections 6.5 and Miscellaneous Examples carry the heaviest exam weight. The optimisation case studies (open box, cone in sphere, isosceles triangle, post-and-string problem) are the two most repeated long-answer slots in CBSE 2021 to 2025.
Application of Derivatives Weightage Compared Across Class 12 Mathematics Chapters
Typical CBSE marks across all 13 chapters of the 2026-27 Class 12 Mathematics book, averaged over the last five Board papers.
Application of Derivatives sits in the upper-middle band of the Calculus unit. In CBSE 2025, these notes contributed 6 marks across one MCQ, one 3-mark rate-of-change problem, and one 3-mark monotonicity assertion-reason.

Ans. Yes. This page hosts these notes, and reflects the current 2026-27 syllabus for Class 12 Mathematics. The chapter now runs 40 pages with six numbered sections, after the Mean Value Theorem sub-section and the dedicated Tangents-Normals and Approximations sections were trimmed from the new edition.
Ques. How many pages is the Class 12 Maths Application of Derivatives NCERT Book PDF?
Ans. The chapter PDF is 40 pages long, covering six sections (Introduction, Rate of Change, Increasing-Decreasing Functions, Maxima-Minima theory, Maximum-Minimum on closed intervals, plus a Miscellaneous Examples section), a Miscellaneous Exercise, Summary, and a Historical Note on Fermat.
Ques. How many solved examples and exercises does Class 12 Maths Chapter 6 have?
Ans. Chapter 6 contains 49 solved examples (including the Miscellaneous Examples block), Exercise 6.1 (18 questions), Exercise 6.2 (19 questions), Exercise 6.3 (27 questions), and a Miscellaneous Exercise (18 questions). All four question sets are within the 2026-27 syllabus.
Ques. What was removed from Class 12 Chapter 6 Application of Derivatives in the new NCERT?
Ans. The current edition removed the dedicated Tangents-Normals and Approximations sections (the concepts are now referenced only briefly inside solved examples), and dropped the Mean Value Theorem (Rolle's and Lagrange) sub-section entirely. The kept content focuses on rate of change, monotonicity, and maxima-minima.
Ques. How many marks does Application of Derivatives carry in CBSE Class 12 Maths Boards?
Ans. The chapter typically contributes 5 to 7 marks in the Class 12 Maths Board paper, usually split as one or two short answers (rate of change or monotonicity) plus one 5-mark long answer on optimisation (open box, cone in sphere, or wire-cut-into-shapes).
Ques. Is Application of Derivatives important for JEE Main?
Ans. Yes. Application of Derivatives contributes 6 to 8 percent of the JEE Main Mathematics section, with 2 to 3 questions per shift, typically on monotonicity, tangents-normals, maxima-minima with constraint, or rate-of-change applications.
Ques. What is the second-derivative test in Class 12 Chapter 6?
Ans. Let $c$ be a critical point of $f$ with $f'(c) = 0$. Then if $f''(c) < 0$, $c$ is a local maximum; if $f''(c) > 0$, $c$ is a local minimum; if $f''(c) = 0$, the test fails and you fall back to the first-derivative sign-change test.
