Study Notes
Definition
- An integral is a mathematical operation that computes the area between a function and the x-axis within a specified interval.
- It is a fundamental concept in calculus, serving as the reverse operation of differentiation.
Types of Integrals
- Definite Integral: A definite integral has a specific upper and lower bound, and is denoted as ∫[a, b] f(x) dx.
- Indefinite Integral: An indefinite integral, also known as an antiderivative, is a function that can be differentiated to obtain the original function.
Notations
- ∫f(x) dx: The most common notation for an integral, where f(x) is the function being integrated.
- ∫[a, b] f(x) dx: The notation for a definite integral, where a and b are the lower and upper bounds respectively.
Basic Properties
- Linearity: The integral of a linear combination of functions is the linear combination of their integrals.
- Additivity: The integral of a function over a sum of intervals is the sum of the integrals over each interval.
- Homogeneity: The integral of a function multiplied by a constant is the constant multiplied by the integral of the function.
Integration Rules
- Power Rule: ∫x^n dx = (x^(n+1))/(n+1) + C
- Product Rule: ∫u dv = uv - ∫v du
- Chain Rule: ∫f(g(x))g'(x) dx = ∫f(u) du, where u = g(x)
Applications of Integrals
- Area Between Curves: Integrals can be used to find the area between two curves.
- Volume of Solids: Integrals can be used to find the volume of solids formed by rotating a region around an axis.
- Work and Energy: Integrals can be used to find the work done by a force and the energy of an object.
