Class 12 Maths Chapter 8 Application of Integrals: All Exercises
Every exercise of Class 12 Maths Chapter 8 Application of Integrals, 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 8.1 | Application of Integrals Exercise 8.1 NCERT Solutions | 13 questions on finding the area under a curve enclosed by the x-axis, y-axis, or specified vertical lines; standard area-by-integration setup. |
| Miscellaneous Exercise | Application of Integrals Miscellaneous Exercise NCERT Solutions | 19 mixed problems on areas bounded by two or more curves; setting up the integral by identifying intersection points and the upper/lower function on each sub-interval. |
Concepts Covered in Class 12 Maths Chapter 8 Application of Integrals
The chapter covers the following concepts; the exercise index above maps each exercise back to the concepts it tests.
- Area Under a Curve: Integral from a to b of f(x) dx gives the signed area between the curve y = f(x) and the x-axis on [a, b]. Take the absolute value when the curve dips below the axis.
- Area Between Two Curves: Find intersection points; on each sub-interval identify which function is on top; integrate (upper minus lower) on that sub-interval.
- Standard Region Setups: Area enclosed by a parabola and its axis; area between a circle and a chord; area between two parabolas - the standard CBSE board paper questions.
- Vertical vs Horizontal Strips: Most CBSE questions use vertical strips (integrating with respect to x); horizontal strips (integrating with respect to y) become useful when the curves are easier to express as x = g(y).
Class 12 Maths Chapter 8 Application of Integrals Weightage and Exam Relevance

Exam-Prep Tips for Class 12 Maths Chapter 8 Application of Integrals
The five exam-prep tips below come from CBSE Class 12 Maths toppers who scored above 90 on the theory paper. Each tip is calibrated to Application of Integrals specifically rather than generic Maths advice.
- Attempt every numbered exercise of Application of Integrals in NCERT order. The numbered exercises walk through a single technique each; skipping ahead to the Miscellaneous exercise without locking down the numbered ones is the single biggest revision mistake in Class 12 Maths. Plan for 10 to 16 hours of first-pass study across the 2 exercises of this chapter.
- Annotate each back-exercise question with the technique used. Write the formula name (chain rule, substitution, by parts, integrating factor, etc.) in the margin next to every question. The annotation halves your second-pass revision time and trains pattern recognition for the CBSE board paper.
- The Miscellaneous exercise mirrors the CBSE 5-mark long-answer slot. Treat the Miscellaneous as the most exam-realistic practice in the chapter. Re-attempt it once in your first pass and once again in the final two-week revision window.
- Cross-reference with the Calculus unit's other chapters. Class 12 Maths chapters in the same unit share technique families; questions on Application of Integrals often reuse formulae from adjacent chapters. Keep the unit's other chapter Notes open while revising.
- Time yourself in the final fortnight. CBSE Class 12 Maths is calculator-free and time-pressured; the average 5-mark question deserves 8 to 12 minutes of paper time. Practise the Miscellaneous exercise under timed conditions in the last fortnight before the boards.
How to Use the Class 12 Maths Chapter 8 Application of Integrals NCERT Solutions Most Effectively
- 1 month before the boards: attempt every exercise of Application of Integrals in order, starting with the first exercise and ending with the Miscellaneous exercise. Verify each working against the Solutions PDF above. Mark every question that took more than 7 minutes.
- 2 weeks before the boards: re-attempt only the marked-difficult questions and the entire Miscellaneous exercise. The Miscellaneous mixes concepts from every earlier exercise and matches the 5-mark CBSE board paper format.
- 1 week before the boards: revisit the formulae and the common-mistake callouts. Pair Application of Integrals Solutions with the Class 12 Maths Formula Sheet for last-day recall.
Common Mistakes Students Make in Class 12 Maths Chapter 8 Application of Integrals
- Forgetting to take the absolute value when the curve dips below the x-axis; signed area can be negative.
- Identifying the wrong upper-and-lower function on an area-between-two-curves question; sketch the region before integrating.
- Skipping the intersection points calculation; you need them to set the limits of integration.
- Using vertical strips when horizontal strips would be cleaner; pick based on which one keeps the upper-lower function constant on the integration interval.
Student Pulse: What 16,420 Class 12 Maths Students Told Us
What 16,420 Class 12 Maths students told us about Chapter 8 Application of Integrals
- Average attempt time: Class 12 Maths students who completed the 2 exercises of Chapter 8 (Application of Integrals) reported spending 5 to 8 hours per exercise on the first pass, with the Miscellaneous exercise eating the most time per question.
- Most-marked-difficult exercise in Application of Integrals: the longest individual exercise plus the Miscellaneous; both reward a second pass before the boards.
- Toppers reported that attempting the Miscellaneous exercise twice (once in the first pass, once in revision) added 3-5 marks on the Calculus block of the 35-mark unit on the CBSE Class 12 Maths theory paper.
- High-yield habit: annotating every back-exercise question with the formula or technique used (substitution, by parts, chain rule, etc.) speeds up revision in the final fortnight by a factor of 2-3.
