The file ANTID > contains a routine for evaluating integrals of expressions involving an arbitrary unspecified function and its derivatives. After BATCH'ing the file, it may be used by: ANTIDIFF(G,X,U(X)); where G is the expression involving U(X) (U(X) arbitrary) and its derivatives, whose integral with respect to X is desired. The batch file also defines the functions NONZEROANDFREEOF and LINEAR as well as ANTID. ANTID is the same as ANTIDIFF except that it returns a list of two parts, the first part is the integrated part of the expression and the second part of the list is the non- integrable remainder. A translated version of this file is available as SHARE2;ANTID LISP. It may be used by LOADFILE(ANTID,LISP,SHARE2). Send complaints to BNLGHC.
