Topics in Definite Integration
1
Definite Integration as Limit of Sum
- Definite integral represents area under curve y = f(x) between x = a and x = b
- ∫[a to b] f(x)dx = lim[n→∞] h∑[r=0 to n-1] f(a + rh) where h = (b-a)/n
- Can be calculated using upper sum or lower sum - both give same result
2
Fundamental Theorems of Integral Calculus
- First Fundamental Theorem: If F(x) = ∫[a to x] f(t)dt, then F'(x) = f(x)
- Second Fundamental Theorem: ∫[a to b] f(x)dx = F(b) - F(a) where F'(x) = f(x)
- Area function F(x) represents area from fixed point to variable point
3
Properties of Definite Integration
- ∫[a to b] f(x)dx = -∫[b to a] f(x)dx (reversing limits changes sign)
- ∫[a to b] f(x)dx = ∫[a to c] f(x)dx + ∫[c to b] f(x)dx (splitting limits)
- ∫[a to b] f(x)dx = ∫[a to b] f(a+b-x)dx (substitution property)
4
Integration by Parts for Definite Integrals
- ∫[a to b] u dv = [uv]ₐᵇ - ∫[a to b] v du
- Choose u using ILATE rule (Inverse, Logarithmic, Algebraic, Trigonometric, Exponential)
- Often used for products of different types of functions
