3.1: Introduction to Integration

MACSYMA has several routines for handling integration. The INTEGRATE command makes use of most of them. There is also the ANTID package, which handles an unspecified function (and its derivatives, of course). For numerical uses, there is the ROMBERG function, and the IMSL version of Romberg, DCADRE. There is also an adaptave integrator which uses the Newton-Cotes 8 panel quadrature rule, called QUANC8. Hypergeometric Functions are being worked on, do DESCRIBE(SPECINT); for details. Generally speaking, MACSYMA only handles integrals which are integrable in terms of the "elementary functions" (rational functions, trigonometrics, logs, exponentials, radicals, etc.) and a few extensions (error function, dilogarithm). It does not handle integrals in terms of unknown functions such as g(x) and h(x).
