Study Notes
Integral Calculus
- Integral calculus reverses differentiation; finding a function (F(x)) whose derivative (F'(x)) is a given function (f(x)).
- Indefinite integrals: The set of all functions (F(x) + C) whose derivative is a given function (f(x)), where C is the integration constant.
- Integration rules mirror differentiation rules: Constant multiples can be moved outside the integral; integrals of sums are sums of integrals.
Integration Rules
- ∫ adx = ax + C
- ∫ xa dx = (1/(a+1))x(a+1) + C, where a ≠ -1
- ∫ex dx = ex + C
- ∫eax dx = (1/a)eax + C, where a ≠ 0
- ∫ax dx = ((1/ln a))ax + C, where a > 0, a ≠ 1
- ∫(1/x) dx = ln|x| + C
Chain Rule
- ∫ f'(x)/f(x) dx = ln|f(x)| + C, for f(x) > 0
Partial Integration
- Reverses the product rule: ∫ f(x)g'(x) dx = f(x)g(x) − ∫f'(x)g(x) dx
- Simplifies calculating integrals by transforming them into potentially simpler ones.
Definite Integrals
- Definite integral calculates the area under a curve between two points (a and b)
- ∫ab f(x) dx = F(b) - F(a), where F(x) is the antiderivative of f(x).
Key Considerations for Definite Integrals
- Functions must be continuous over the interval [a, b].
- Exchanging limits reverses the sign.
- Splitting the interval [a, b] into [a, c] and [c, b] applies to definite integrals.
- If a = b, the area is 0.
- Constant factors and sums apply to definite integrals.
Solids of Revolution
- Volume of a revolved solid: V = π∫ab f(x)2 dx
- Arc Length: L = ∫ab √(1 + (f'(x))2) dx
- Lateral Surface Area: M = 2π∫ab f(x)√(1 + (f'(x))2) dx
Hop Plant Growth Example
- Hop plant growth follows different linear functions over defined time intervals.
- The definite integral calculation on those intervals found the total height of the plant.
