Study Notes
Integration and Its Properties
- Integration is the inverse process of differentiation
- Anti-derivatives are functions that could have possibly given a function as a derivative
- Indefinite integral gives all the anti-derivatives of a function
- Definite integral finds a numerical value for an area under a curve
- Integration formulas are used for evaluating indefinite and definite integrals in calculus
Integration as an Inverse Process of Differentiation
- If the derivative of F(x) is equal to f(x), then F(x) is called the integral of f(x)
- F(x) + C is also an anti-derivative of f(x), where C is an arbitrary constant (constant of integration)
- There exist infinitely many anti-derivatives of a function
Symbols/Terms/Phrases related to integration
- ∫f(x)dx: Integral of f with respect to x
- f(x): Integrand
- x: Variable of integration
- Integrate: Find the integral
- Integral of f(x): A function F such that F'(x) = f(x)
- Constant of integration: An arbitrary constant
Some Standard Formulae
- ∫xⁿdx = (xⁿ⁺¹)/(n+1) + C, where n ≠ -1
- ∫sin x dx = -cos x + C
- ∫cos x dx = sin x + C
- ∫sec² x dx = tan x + C
- ∫cosec² x dx = -cot x + C
- ∫sec x tan x dx = sec x + C
- ∫cosec x cot x dx = -cosec x + C
- ∫ex dx = ex + C
- ∫1/x dx = ln|x| + C
