Risch’s algorithm for integration We want to integrate −ex − x + ln(x)x + ln(x)xex f := x(ex + x)2 The elementary field we obtain is Q(x)(q1, q2) with q1 = ex, q2 = ln(x), and so the integrand …

And we were taught wrong. The Risch algorithm (which is known for decades) allows one to find, in a finite number of steps, if a given indefinite integral can be taken in elementary functions,
Risch’s original algorithm requires polynomial factorization over the constant field as well as testing for integrality, but it has been shown by M. Rothstein [7, 8] that the computation of …
