Abstract

In this note, we look at the extension to the parallel Risch algorithm (see, e.g., the papers by Norman & Moore [1977], Norman & Davenport [1979], ffitch [1981] or Davenport [1982] for a description of the basic algorithm) which represents trigonometric functions in terms of tangents, rather than instead of complex exponentials.
