Key Concepts

Direct Integration

Direct integration is the method of evaluating an integral by finding the antiderivative of the integrand directly using standard formulas and techniques. It is often applied when the integrand is composed of elementary functions, making the integral straightforward to compute without the need for substitution or integration by parts.

Fundamental Theorem of Calculus

The Fundamental Theorem of Calculus bridges differentiation and integration by stating that if a function is continuous over an interval, its definite integral over that interval can be calculated by taking the difference of an antiderivative evaluated at the endpoints. This theorem is fundamental because it provides a practical way to compute the net accumulation of a function without directly taking limits of sums.

Definite Integral

A definite integral represents the accumulated net area under a function’s graph over a closed interval. It is computed as the limit of Riemann sums and provides a numerical value that corresponds to the total accumulation of the quantity described by the function between the specified limits.

Antiderivative

An antiderivative of a function is another function whose derivative equals the original function. Finding an antiderivative is the key step in evaluating a definite integral, as it is used in the process of reversing differentiation.
