Get the Class 12 Maths Handwritten Notes PDF below for Class 12 Mathematics Chapter 7 Integrals. The handwritten format makes the Class 12 Maths Handwritten Notes PDF useful as a revision companion to the typed Notes page on the same topic, since each formula appears in a coloured box alongside its derivation.
- CBSE Weightage: 8 to 10 marks (Chapter 7 Integrals plus Chapter 8 Application of Integrals together form the Calculus unit worth roughly 18 marks; expect one 3-marker on substitution or by-parts, one 3-marker on definite-integral properties, and one 5-marker mixing partial fractions or special integrals)
- JEE Main Weightage: 8 to 10% (2 to 3 questions per shift on indefinite integrals, by-parts, partial fractions, and definite-integral properties; among the top three highest-yield Maths chapters)
- JEE Main Weightage: Not in JEE Main syllabus (Maths-only chapter; high weight for JEE Main, JEE Advanced, and CUET Mathematics)
The notebook opens with the antiderivative definition and the family of curves picture, locks in the standard-integrals table, then walks through substitution, partial fractions, integration by parts with the ILATE rule, five special integrals, and the six properties of definite integrals, ending with a one-page summary card.
These handwritten notes are prepared by Collegedunia subject mentors, mapped to the 2026-27 NCERT print, and cross-checked against the last five years of CBSE Board and JEE Main papers on Integrals.

Class 12 Maths Handwritten Notes PDF - Frequently Asked Questions
Ques. Where can I download the Class 12 Maths Handwritten Notes PDF for free?
Ans. You can download the Integrals Class 12 Maths Handwritten Notes PDF directly from the Class 12 Maths Handwritten Notes PDF. Both the Normal and HD versions are available, and both are free.
Ques. Is this Class 12 Maths Handwritten Notes PDF aligned with the 2026-27 NCERT syllabus?
Ans. Yes. The notebook reflects the current 2026-27 syllabus for Class 12 Mathematics. NCERT retains Chapter 7 Integrals in full, namely antiderivatives, the standard-integrals table, substitution, partial fractions, integration by parts, special integrals, the Fundamental Theorem of Calculus, and the six properties of definite integrals. The handwritten layer flags every sub-topic CBSE has tested in every Board paper since 2022.
Ques. How many pages is the Class 12 Maths Integrals Handwritten Notes PDF?
Ans. The handwritten notes PDF runs 4 pages and covers antiderivatives with a family-of-curves sketch, the 11 standard integrals in a dashed grid, the substitution method with a solved examples, integration by parts with the ILATE priority ladder, partial fractions across three standard templates, five special integrals, the Fundamental Theorem of Calculus with an area-under-curve sketch, and the six properties of definite integrals on a single page, ending with a one-page revision card.
Ques. What is the difference between definite and indefinite integrals?
Ans. An indefinite integral ∫ f(x) dx = F(x) + C returns a family of antiderivatives parameterised by the constant of integration C.
A definite integral ab f(x) dx = F(b) - F(a) returns a single number, the net signed area between the curve y = f(x) , the x-axis, and the vertical lines x = a and x = b .
Page 1 of the notebook draws the antiderivative family; page 4 draws the definite-integral area panel and the Fundamental Theorem of Calculus.
Ques. How do I choose u and dv in integration by parts?
Ans. Use the ILATE rule. The five categories are Inverse-trigonometric, Logarithmic, Algebraic, Trigonometric, and Exponential. Whichever function in your integrand sits earliest in this list becomes u; the rest, including the dx, becomes dv.
So in ∫ x log x dx , Logarithmic beats Algebraic, hence u = log x and dv = x dx . The notebook shows the ILATE ladder as a vertical priority chart on page 3.
Ques. Do these handwritten notes help with JEE Main Integrals questions?
Ans. Yes. JEE Main draws 2 to 3 questions per shift from Integrals, and the yellow MCQ-trap boxes in the notebook is calibrated against the last five years of JEE Main papers.
The covered traps include the odd-function-on-symmetric-interval shortcut, the King-rule property, the ex[f(x) + f'(x)] shortcut, the scaling-rule pitfalls, and partial-fraction setup with the wrong template. Together with the standard-integrals box, these account for the bulk of JEE Main Integrals questions.
Ques. What is the difference between Collegedunia's Handwritten Notes and the regular Notes for Class 12 Maths Chapter 7?
Ans. The regular typed Notes carry the deep concept walk-through with the full antiderivative theory, the Fundamental Theorem of Calculus proof, and every property derivation.
These Handwritten Notes compress the same content into a faster, more visual revision tool with dashed formula boxes, the ILATE ladder, the special-integrals dashed box, and a 24-hour pre-exam recall card. Use the typed Notes for first read, then these for two recall passes.
Ques. Which sub-topic of Integrals carries the most weight in CBSE Board exams?
Ans. The 5-mark Board question almost always comes from one of two places, namely a definite-integral evaluation using the six properties (especially the King rule 0a f(x) dx = 0a f(a-x) dx ) or an indefinite integral that combines partial fractions with one of the five special-integral templates.
Together these two sub-topics account for roughly 5 of the 8 to 10 marks CBSE assigns to this chapter. The notebook places its King-rule callout and partial-fraction template box on exactly these two sub-topics.
