Integration refers to the process of combining or incorporating different elements or parts into a unified whole. In mathematics, integration refers to the process of finding the integral of a function, which involves calculating the area under the curve of the function. In a broader sense, integration can also refer to the process of bringing together different ideas, perspectives, or systems to create a cohesive and harmonious whole.

Integration in mathematics refers to finding the area under the curve of a function. It is the reverse operation of differentiation. The symbol for integration is ∫, which resembles an elongated S, and integration is often denoted as ∫f(x) dx, where f(x) is the function being integrated and dx represents the differential of the independent variable x.
Meaning of Integration:
- Geometric Interpretation: Integration finds the area under the curve of a function. This area can represent various quantities, such as the volume of a solid, the work done by a force, or the probability of an event.
- Formulaic Interpretation: Integration is the process of finding an antiderivative of a function. An antiderivative is a function whose derivative is the original function.
- Definite vs. Indefinite Integration:
- Definite Integration: Finds the area under the curve of a function over a specific interval [a, b]. The result is a definite number.
- Indefinite Integration: Finds an antiderivative of a function without specifying the interval of integration.
Applications of Integration:
Integration has numerous applications in various fields, including:
- Calculus: Finding areas, volumes, lengths, and other geometric properties.
- Physics: Calculating work, energy, and forces.
- Engineering: Designing structures, bridges, and machines.
- Economics: Analyzing demand, supply, and consumer behavior.
- Probability and Statistics: Calculating probabilities, means, and variances.
Fundamental Theorem of Calculus:
The Fundamental Theorem of Calculus connects integration and differentiation. It states that if f is a continuous function on an interval [a, b], then the area under the curve of f from a to b is given by the definite integral ∫[a, b] f(x) dx, and that the antiderivative of f is F(x) = ∫f(x) dx.
