Class 11 Maths Formula List

This section covers the complete list of formulas that are commonly asked in CBSE Class 11 exams and competitive tests like JEE. These formulas are organized chapter-wise for quick revision.

Chapter-wise Maths Formulas

1. Sets Formulas Class 11

• n(A ∪ B) = n(A) + n(B) – n(A ∩ B)
• (A ∩ B)’ = A’ ∪ B’
• Important laws: De Morgan's Law, Distributive Law

2. Relations and Functions Formulas

• Function f: A → B is defined as a relation where every element in A has a unique image in B.
• Domain, Codomain, Range

3. Trigonometric Functions Formulas

• sin²θ + cos²θ = 1
• 1 + tan²θ = sec²θ
• sin(2A) = 2sinAcosA

4. Principle of Mathematical Induction Formulas

• Prove for P(1)
• Assume P(k) is true
• Prove P(k+1)

5. Complex Numbers and Quadratic Equations

• i² = –1
• (a + bi)(a – bi) = a² + b²

6. Linear Inequalities Formulas

• If a > b and c > 0, then ac > bc
• Graphical solution: Use shading on number line/plane

7. Permutations and Combinations Formulas

• nPr = n! / (n–r)!
• nCr = n! / [(n–r)! × r!]

8. Binomial Theorem Formulas

• (a + b)ⁿ = Σ nCr × aⁿ⁻ʳ × bʳ
• General term: T_r+1 = nCr × aⁿ⁻ʳ × bʳ

9. Sequences and Series Formulas

• Arithmetic Progression: a_n = a + (n–1)d
• Sum: S_n = n/2 [2a + (n–1)d]

10. Straight Lines and Conic Sections

• Slope of line: m = (y₂ – y₁)/(x₂ – x₁)
• Circle: x² + y² = r²

11. Limits and Derivatives Formulas

• lim_x→a (f(x)) = L
• Derivative of xⁿ = nx^n–1

12. Statistics and Probability Formulas

• Mean = Σx / n
• Probability = (Favorable outcomes) / (Total outcomes)
