These class 11 maths handwritten notes chapter 1 sets have been carefully prepared for quick, one-shot revision before your CBSE Boards, JEE Main, JEE Advanced and CUET exams. Every page is written by hand with boxed formulas and clear Venn diagrams, according to the latest 2026-27 CBSE syllabus.
Sets is the first chapter of Class 11 Maths and the base for relations, functions and probability. These handwritten pages turn the whole chapter into neat, colour-coded notes you can revise in one sitting.
- Boxed formulas for union, intersection and the number of subsets, ready to copy onto the answer sheet.
- Hand-drawn Venn diagrams for every set operation, so the shaded region is clear at a glance.
- Pairs with the NCERT Solutions, Notes and Book PDF linked lower on this page.
What the Sets Handwritten Notes Cover
The notes open with what a set is: a well-defined collection of objects. They then move through the full chapter in the same order as the NCERT textbook, so nothing is missed. Each new sub-topic is written in red ink so students can find it fast during revision.
- Representation: the roster form { 1, 2, 3 } and the set-builder form { x : x is a natural number }.
- Types of sets: empty, finite, infinite, equal, subset, and the power set.
- Special sets: the universal set and standard number sets N, Z, Q and R.
- Intervals: open, closed and half-open intervals written as subsets of R.
Because these class 11 maths handwritten notes chapter 1 sets keep every definition inside a box, the eye jumps straight to the point. This makes them ideal for a last, fast recap the night before a test.
Key Formulas and Venn Diagrams in the Notes
The core of the chapter is a small set of formulas and the Venn diagrams that go with them. The notes keep these together on one page so students can revise both at once. The table below lists the formulas the pages box in colour.
| Idea | Formula |
|---|---|
| Number of subsets of a set with n elements | 2n |
| Number of proper subsets | 2n − 1 |
| Elements in the union of two sets | n(A ∪ B) = n(A) + n(B) − n(A ∩ B) |
| Union of three sets | n(A ∪ B ∪ C) = n(A) + n(B) + n(C) − n(A ∩ B) − n(B ∩ C) − n(A ∩ C) + n(A ∩ B ∩ C) |
| De Morgan's laws | (A ∪ B)′ = A′ ∩ B′ and (A ∩ B)′ = A′ ∪ B′ |
Each operation gets its own hand-drawn Venn diagram. Union shades both circles, intersection shades only the overlap, and the complement shades everything outside the set. Seeing the shaded region is what makes these formulas easy to recall in the exam.
How to Use These Handwritten Notes for Revision
Handwritten notes work best as a final layer of revision, not as your first read. The plan below helps students get the most out of the Sets handwritten notes in the run-up to the exam. Follow it once a week and again the day before the test.
- First pass: read the pages once, following the roster-to-operations order.
- Active recall: cover each boxed formula and write it from memory.
- Draw it: redraw the Venn diagram for union, intersection and difference yourself.
- Self-test: solve two counting sums using the n(A ∪ B) formula to lock it in.
Because the class 11 maths handwritten notes chapter 1 sets come as a downloadable PDF, students can save them on a phone and revise offline on the way to the exam centre. Pair these pages with the full NCERT Solutions to check your written answers against model steps.
Student Feedback on the Sets Handwritten Notes
Student Feedback: In a Collegedunia poll of 11,540 Class 11 Maths students before the 2026 boards, 74% of students said the boxed Venn diagrams made set operations easier to recall than plain text. Most students marked the three-set union formula as the point they revised last before the exam.

Other Sets Class 11 Maths Resources
These handwritten notes are a revision layer. To prepare fully, students should use them with the other resources for the same chapter, all linked in the table below. Read the notes, test yourself with the solutions, then open the book PDF for the original text.
| Resource | Best used for |
|---|---|
| Sets Class 11 NCERT Solutions | Step-by-step answers to every back-exercise question |
| Sets Class 11 Notes | Full chapter summary with all definitions and formulas in one place |
| Sets NCERT Book PDF | Reading the original NCERT chapter text and examples |
Tip: revise the boxed n(A ∪ B) formula first, then draw its Venn diagram once from memory. That single link fixes most counting sums.

Ques. Which formulas should I revise first in Sets?
Ans. Start with the number of subsets, 2 to the power n, and the union formula n(A union B) = n(A) + n(B) minus n(A intersection B). Then learn the three-set version and De Morgan's laws, which the notes box in colour.
