JEE Main Maths Formulas 2026

This section covers fundamental formulas for quick revision. Understanding and applying these formulas are crucial for JEE Main preparation.

Quadratic Equations

Quadratic equations are central to many mathematical problems.

  • Standard Form: ax^2 + bx + c = 0

  • General Equation for Roots: x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

  • Sum of Roots: -\frac{b}{a}

  • Product of Roots: \frac{c}{a}

  • Discriminant (\Delta): \Delta = b^2 - 4ac

Trigonometric Identities

Basic trigonometric identities are frequently used.

  • Pythagorean Identity: \sin^2(x) + \cos^2(x) = 1

  • Tangent Identity: 1 + \tan^2(x) = \sec^2(x)

  • Cotangent Identity: 1 + \cot^2(x) = \csc^2(x)

Limits

Understanding limits is foundational for calculus.

  • Limit of Sum/Difference: \lim(f(x) \pm g(x)) = \lim f(x) \pm \lim g(x)

  • Limit of Product: \lim(f(x)g(x)) = \lim f(x) \times \lim g(x)

  • Limit of Quotient: \lim\left(\frac{f(x)}{g(x)}\right) = \frac{\lim f(x)}{\lim g(x)}, \text{ if } \lim g(x) \neq 0

Differentiation Rules

These are key for calculating derivatives.

  • Power Rule: \frac{d}{dx}(x^n) = nx^{n-1}

  • Sum/Difference Rule: \frac{d}{dx}(f(x) \pm g(x)) = f'(x) \pm g'(x)

  • Product Rule: \frac{d}{dx}(f(x)g(x)) = f'(x)g(x) + f(x)g'(x)

  • Quotient Rule: \frac{d}{dx}\left(\frac{f(x)}{g(x)}\right) = \frac{g(x)f'(x) - f(x)g'(x)}{(g(x))^2}

Integration Formulas

Basic integration forms are essential.

  • Power Rule: \int x^n dx = \frac{x^{n+1}}{n+1} + C, \text{ for } n \neq -1

  • Logarithmic Rule: \int \frac{1}{x} dx = \log_e |x| + C

  • Exponential Rules: \int e^x dx = e^x + C \int a^x dx = \frac{a^x}{\log_e a} + C

Probability

Core probability formulas are critical for this section.

  • Union of Events: P(A \cup B) = P(A) + P(B) - P(A \cap B)

  • Intersection of Independent Events: P(A \cap B) = P(A) \times P(B|A)

  • Conditional Probability: P(A|B) = \frac{P(A \cap B)}{P(B)}

Limit Rules for Functions

Limits apply fundamental arithmetic operations. The limit of a sum, difference, product, or quotient of functions is the sum, difference, product, or quotient of their individual limits, provided the individual limits exist and the denominator limit is non-zero for quotients. These rules simplify complex limit calculations.

Differentiation Rules

Differentiation rules provide methods to find the derivative of various functions. The power rule applies to polynomial terms. The sum/difference rule allows differentiating term by term. The product and quotient rules are used for functions multiplied or divided, respectively. These rules form the backbone of differential calculus.
