Key Topics to Revise
1
Basic Concepts and Standard Formulas
- 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 always added to indefinite integrals
- ∫[f(x) ± g(x)]dx = ∫f(x)dx ± ∫g(x)dx (Linearity property)
2
Integration by Substitution
- Substitution method transforms difficult integrals into simpler standard forms
- Two main types: Direct substitution and Integration of f(g(x))g'(x)
- Choose substitution that simplifies the integrand significantly
3
Integration of Trigonometric Functions
- Powers of sin x and cos x require different strategies based on the powers
- Product-to-sum formulas useful for products of trigonometric functions
- Trigonometric identities often needed to convert to integrable forms
4
Integration by Parts
- Used for integrals of products of two different types of functions
- Formula: ∫u dv = uv - ∫v du
- ILATE rule for choosing first function: Inverse trig, Logarithmic, Algebraic, Trigonometric, Exponential
