The definite integral of a function over an interval is a fundamental concept in calculus that represents the accumulation of quantities, such as area under a curve, over that interval. It is evaluated using the limits of integration and the antiderivative of the function, often employing the Fundamental Theorem of Calculus to connect differentiation and integration.

The area under a curve in a graph represents the accumulation of a quantity, which is calculated using integration in calculus. This concept is crucial in various fields, including physics for determining displacement from velocity-time graphs and in statistics for finding probabilities in probability density functions.

Limits of integration define the range over which an integral is evaluated, determining the interval on the x-axis for definite integrals. They are crucial in calculating the exact area under a curve or the accumulated quantity described by a function over a specified domain.

An antiderivative of a function is another function whose derivative is the original function, essentially reversing the process of differentiation. It is a fundamental concept in calculus, forming the basis of integral calculus where finding the antiderivative allows for the calculation of definite integrals and the area under curves.

antiderivative

The Fundamental Theorem of Calculus bridges the concepts of differentiation and integration, showing that they are inverse processes. It states that if a function is continuous on a closed interval, then its definite integral can be computed using its antiderivative evaluated at the boundaries of the interval.
