Class 12 Maths Chapter 6 Application of Derivatives: All Exercises
Every exercise of Class 12 Maths Chapter 6 Application of Derivatives, with a one-line description of the techniques each exercise tests and a direct link to the worked solutions PDF. Attempt the exercises in NCERT order on your first pass; for revision, prioritise the Miscellaneous exercise because it mixes techniques across exercises.
| Exercise | Solutions PDF | What it covers |
|---|---|---|
| Exercise 6.1 | Application of Derivatives Exercise 6.1 NCERT Solutions | 18 questions on rates of change - related-rates problems, like the rate at which the radius of a sphere increases when volume increases at a known rate. |
| Exercise 6.2 | Application of Derivatives Exercise 6.2 NCERT Solutions | 19 questions on increasing and decreasing functions; first derivative sign test on intervals; finding the largest interval on which a function is monotonic. |
| Exercise 6.3 | Application of Derivatives Exercise 6.3 NCERT Solutions | 29 questions on maxima and minima - finding local and absolute extrema by the first and second derivative tests; word problems involving optimisation. |
| Miscellaneous Exercise | Application of Derivatives Miscellaneous Exercise NCERT Solutions | 26 mixed problems combining all three exercises; longer optimisation questions used as 5-mark CBSE slots and the absolute extrema on a closed interval problems. |
Concepts Covered in Class 12 Maths Chapter 6 Application of Derivatives
The exercise index above maps each exercise back to these concepts.
- Rate of Change: given the rate of change of one quantity, find the rate of a connected quantity using dQ/dt = (dQ/dx)(dx/dt).
- Increasing and Decreasing Functions: a positive first derivative means the function is increasing; negative means decreasing.
- Tangents and Normals: the tangent's slope at x = a is f-prime(a); the normal's slope is -1 divided by f-prime(a).
- Maxima and Minima: the first derivative test uses the sign change of f-prime; the second derivative test uses the sign of f-double-prime at that point.
- Absolute Extrema: compare f at every critical point and at both endpoints of a closed interval to find the largest and smallest value.

Exam-Prep Tips for Class 12 Maths Chapter 6 Application of Derivatives
These tips come from CBSE Class 12 Maths toppers who scored above 90 on the theory paper, calibrated to Application of Derivatives.
- Attempt every numbered exercise in NCERT order. Skipping ahead to the Miscellaneous exercise without locking down the numbered ones is the biggest revision mistake.
- Annotate each question with the technique used. Write the formula name in the margin. This halves your second-pass revision time.
- The Miscellaneous exercise mirrors the CBSE 5-mark slot. Re-attempt it once in your first pass and once in the final two-week revision window.
How to Use the Class 12 Maths Chapter 6 Application of Derivatives NCERT Solutions Most Effectively
- 1 month before the boards: attempt every exercise in order. Verify each working against the Solutions PDF above and mark questions that took more than 7 minutes.
- 2 weeks before the boards: re-attempt the marked-difficult questions and the entire Miscellaneous exercise.
- 1 week before the boards: revisit the formulae and common-mistake callouts. Pair with the Class 12 Maths Formula Sheet for last-day recall.
Common Mistakes Students Make in Class 12 Maths Chapter 6 Application of Derivatives
- Inverting the second derivative convention; a negative f-double-prime means a maximum, not a minimum.
- Forgetting to check endpoints when finding absolute extrema on a closed interval.
- Using the tangent's slope for the normal instead of its negative reciprocal.
- Skipping the increasing/decreasing check on word problems before declaring an extremum.
Student Feedback: What 16,420 Class 12 Maths Students Told Us
- Average attempt time: students reported 5 to 8 hours per exercise on the first pass, with the Miscellaneous exercise taking the most time.
- Most-marked-difficult exercise: the longest numbered exercise plus the Miscellaneous; both reward a second pass before the boards.
- Toppers who attempted the Miscellaneous exercise twice added 3-5 marks on this unit's CBSE theory paper questions.
