Lockup Calculating Arc Length of Ellipse

[Helge Gabert]

Yes, I know that. The prime could give that answer (4E-3), provided it knows about elliptic integrals, or an approximate value (after issuing an informational message), but certainly not lock up. However, my main point is, why work in CAS, when all you are after is an approximate solution? Do it in Home (or if you really like to work in CAS, put something like 2.0*pi into the limits in order to force an approximate solution). No CAS flags to change.
