Adding the integral of a particular special function is often easy. You probably already know that you can define (in lisp) the integral property of the function as an expression or a function. There are examples in sin.lisp, bessel.lisp and ellipt.lisp. Some time ago I wrote some integral lookup code inspired by Richard Fateman's TILU. I automatically translated part of the TILU table of integrals and added some products of Bessel functions from Gradshteyn and Ryzhik. I should dig it up and put it somewhere. |
