Integration is the basic operation in integral calculus. While differentiation has straightforward rules by which the derivative of a complicated function can be found by differentiating its simpler component functions, integration does not, so tables of known integrals are often useful. This page lists some of the most common antiderivatives. These tables were republished in the United Kingdom in These tables, which contain mainly integrals of elementary functions, remained in use until the middle of the 20th century.

## On the integration of stiff systems of O.D.E.s using extended backward differentiation formulae

In calculus , and more generally in mathematical analysis , integration by parts or partial integration is a process that finds the integral of a product of functions in terms of the integral of the product of their derivative and antiderivative. It is frequently used to transform the antiderivative of a product of functions into an antiderivative for which a solution can be more easily found. The rule can be thought of as an integral version of the product rule of differentiation.

Mathematician Brook Taylor discovered integration by parts, first publishing the idea in The discrete analogue for sequences is called summation by parts. The theorem can be derived as follows. For two continuously differentiable functions u x and v x , the product rule states:. This yields the formula for integration by parts :. This is to be understood as an equality of functions with an unspecified constant added to each side.

It is not necessary for u and v to be continuously differentiable. For instance, if. One can also easily come up with similar examples in which u and v are not continuously differentiable.

Integrating the product rule for three multiplied functions, u x , v x , w x , gives a similar result:. Assuming that the curve is locally one-to-one and integrable , we can define. Thus integration by parts may be thought of as deriving the area of the blue region from the area of rectangles and that of the red region. In particular, this explains use of integration by parts to integrate logarithm and inverse trigonometric functions.

This is demonstrated in the article, Integral of inverse functions. Integration by parts is a heuristic rather than a purely mechanical process for solving integrals; given a single function to integrate, the typical strategy is to carefully separate this single function into a product of two functions u x v x such that the residual integral from the integration by parts formula is easier to evaluate than the single function.

The following form is useful in illustrating the best strategy to take:. On the right-hand side, u is differentiated and v is integrated; consequently it is useful to choose u as a function that simplifies when differentiated, or to choose v as a function that simplifies when integrated.

As a simple example, consider:. The formula now yields:. For example, suppose one wishes to integrate:. The integrand simplifies to 1, so the antiderivative is x. Finding a simplifying combination frequently involves experimentation. In some applications, it may not be necessary to ensure that the integral produced by integration by parts has a simple form; for example, in numerical analysis , it may suffice that it has small magnitude and so contributes only a small error term.

Some other special techniques are demonstrated in the examples below. The same integral shows up on both sides of this equation. The integral can simply be added to both sides to get. A similar method is used to find the integral of secant cubed. Two other well-known examples are when integration by parts is applied to a function expressed as a product of 1 and itself. This works if the derivative of the function is known, and the integral of this derivative times x is also known.

The second example is the inverse tangent function arctan x :. A rule of thumb has been proposed, consisting of choosing as u the function that comes first in the following list: [4]. The function which is to be dv is whichever comes last in the list. The reason is that functions lower on the list generally have easier antiderivatives than the functions above them. In general, one tries to choose u and dv such that du is simpler than u and dv is easy to integrate.

Also, in some cases, polynomial terms need to be split in non-trivial ways. For example, to integrate. Integration by parts is often used as a tool to prove theorems in mathematical analysis. Integration by parts illustrates it to be an extension of the factorial function:. Integration by parts is often used in harmonic analysis , particularly Fourier analysis , to show that quickly oscillating integrals with sufficiently smooth integrands decay quickly.

The most common example of this is its use in showing that the decay of function's Fourier transform depends on the smoothness of that function, as described below. If f is a k -times continuously differentiable function and all derivatives up to the k th one decay to zero at infinity, then its Fourier transform satisfies. The exact constant on the right depends on the convention of the Fourier transform used.

This is proved by noting that. Applying this inductively gives the result for general k. A similar method can be used to find the Laplace transform of a derivative of a function. The above result tells us about the decay of the Fourier transform, since it follows that if f and f k are integrable then. The proof uses the fact, which is immediate from the definition of the Fourier transform , that. If f is smooth and compactly supported then, using integration by parts, we have.

Extending this concept of repeated partial integration to derivatives of degree n leads to. The latter condition stops the repeating of partial integration, because the RHS-integral vanishes. The essential process of the above formula can be summarized in a table; the resulting method is called "tabular integration" [5] and was featured in the film Stand and Deliver. The result is as follows:. The product of the entries in row i of columns A and B together with the respective sign give the relevant integrals in step i in the course of repeated integration by parts.

The complete result is the following with the alternating signs in each term :. In this case the repetition may also be terminated with this index i.

This can happen, expectably, with exponentials and trigonometric functions. As an example consider. Integration by parts can be extended to functions of several variables by applying a version of the fundamental theorem of calculus to an appropriate product rule. There are several such pairings possible in multivariate calculus, involving a scalar-valued function u and vector-valued function vector field V.

The product rule for divergence states:. Rearranging gives:. The regularity requirements of the theorem can be relaxed. From Wikipedia, the free encyclopedia. Method for computing the integral of a product. Limits of functions Continuity. Mean value theorem Rolle's theorem.

This is a summary of differentiation rules , that is, rules for computing the derivative of a function in calculus. Unless otherwise stated, all functions are functions of real numbers R that return real values; although more generally, the formulae below apply wherever they are well defined [1] [2] — including the case of complex numbers C. In Leibniz's notation this is written as:. Combining the power rule with the sum and constant multiple rules permits the computation of the derivative of any polynomial. The reciprocal rule can be derived either from the quotient rule, or from the combination of power rule and chain rule. If f and g are functions, then:. The elementary power rule generalizes considerably.

A class of extended backward differentiation formulae suitable for the approximate numerical integration of stiff systems of first order ordinary differential equations is derived. An algorithm is described whereby the required solution is predicted using a conventional backward differentiation scheme and then corrected using an extended backward differentiation scheme of higher order. An algorithm based on the integration formulae derived in this paper is illustrated by some numerical examples and it is shown that it is often superior to certain existing algorithms.

Выбегая из собора в маленький дворик, он зацепился пиджаком за дверь, и плотная ткань резко заставила его остановиться, не сразу разорвавшись. Он потерял равновесие, шатаясь, выскочил на слепящее солнце и прямо перед собой увидел лестницу. Перепрыгнув через веревку, он побежал по ступенькам, слишком поздно сообразив, куда ведет эта лестница.
