CBSE Class 10 Maths Formula Sheet 2026 – Chapter-wise PDF for Quick Revision

Q: What is the CBSE Class 10 Maths formula sheet and why is it important?

The CBSE Class 10 Maths formula sheet is a compiled list of all important formulas from each chapter. It is important because many board exam questions are directly formula-based, and revising formulas helps students save time, avoid mistakes, and score better.

Q: Which chapters are most important in the CBSE Class 10 Maths formula sheet?

High-weightage chapters in the CBSE Class 10 Maths formula sheet include Trigonometry, Arithmetic Progressions, Surface Areas and Volumes, Statistics, and Geometry. These chapters contribute a significant number of marks and require strong formula recall.

Q: Where can students download the CBSE Class 10 Maths formula sheet PDF?

Students can download the CBSE Class 10 Maths formula sheet PDF from trusted educational platforms and CBSE-aligned websites. Many platforms also provide chapter-wise and exam-ready formula sheets for quick revision before the board exam.

Q: Is the CBSE Class 10 Maths formula sheet different for Maths Basic and Maths Standard?

The CBSE Class 10 Maths formula sheet is mostly the same for both Maths Basic and Maths Standard. However, Maths Standard includes a few advanced applications of formulas, so students opting for Standard should practice deeper problem-solving using the same formulas.

Q: How should students use the CBSE Class 10 Maths formula sheet for last-minute revision?

For last-minute revision, students should revise the CBSE Class 10 Maths formula sheet 2-3 times daily, focus on frequently asked formulas, and solve at least one question per formula. This approach boosts confidence and improves speed during the exam.

The CBSE Class 10 Maths formula sheet is the most effective tool for last-minute revision before board exams. Instead of revising entire chapters, students can quickly recall important concepts by going through formulas that are frequently used in the exam. Below is a chapter-wise list of important formulas that every Class 10 student must revise before the exam.

Why Are Formula Sheets Important for CBSE Class 10 Maths?

Formula sheets help students:

Fill out the form for expert academic guidance

Revise key concepts quickly before the CBSE board exam.
Avoid confusion between similar formulas
Improve speed and accuracy during problem-solving
Gain confidence in high-weightage chapters
Perform better in numerical and application-based questions

Many questions in the Maths exam are directly based on formulas, especially in chapters like Trigonometry, Geometry, and Mensuration.

a₁x + b₁y + c₁ = 0
a₂x + b₂y + c₂ = 0

Consistency condition:

a₁/a₂ ≠ b₁/b₂ → Unique solution
a₁/a₂ = b₁/b₂ = c₁/c₂ → Infinite solutions
a₁/a₂ = b₁/b₂ ≠ c₁/c₂ → No solution

4. Quadratic Equations

Standard form: ax² + bx + c = 0
Quadratic formula: x = (−b ± √(b² − 4ac)) / 2a
Discriminant: D = b² − 4ac

5. Arithmetic Progressions (AP)

n^th term: a_n = a + (n − 1)d
Sum of first n terms: S_n = n/2 [2a + (n − 1)d]

6. Triangles

Pythagoras theorem: a² + b² = c²
Area of similar triangles: Ratio of areas = square of ratio of corresponding sides

7. Coordinate Geometry

Distance formula: √((x₂ − x₁)² + (y₂ − y₁)²)
Section formula (internal): ((mx₂ + nx₁)/(m + n), (my₂ + ny₁)/(m + n))
Area of triangle: 1/2 |x₁(y₂ − y₃) + x₂(y₃ − y₁) + x₃(y₁ − y₂)|

8. Trigonometry

Trigonometric Ratios

sin θ = Opposite / Hypotenuse
cos θ = Adjacent / Hypotenuse
tan θ = Opposite / Adjacent
