Revision Notes — Integrals
Key concepts, formulas, and definitions from Integrals for MHT-CET Mathematics preparation.
Key Topics to Revise
Basic Integration Rules and Standard Forms
- Integration is the inverse of differentiation - if d/dx[F(x)] = f(x), then ∫f(x)dx = F(x) + C
- The constant of integration C is essential in indefinite integrals
- Learn all standard integral formulas by heart as they form the foundation
Integration by Substitution Method
- Used when integrand is in the form f(g(x)) × g'(x) or can be transformed into this form
- Choose substitution u = g(x), then du = g'(x)dx
- Three main types: direct substitution, trigonometric substitution, and algebraic substitution
Integration by Parts
- Used for products of two different types of functions using formula ∫udv = uv - ∫vdu
- ILATE rule for choosing u: Inverse functions, Logarithmic, Algebraic, Trigonometric, Exponential
- Sometimes requires applying integration by parts twice (for functions like e^x sin x)
Integration of Rational Functions by Partial Fractions
- Used when integrand is a proper rational function (degree of numerator < degree of denominator)
- If improper, first divide to get polynomial + proper rational function
- Four cases based on factors of denominator: linear non-repeated, linear repeated, quadratic non-repeated, quadratic repeated
