Category: Lisp Core  Simplification Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Raymond Toy (rtoy) Assigned to: Nobody/Anonymous (nobody) Summary: elliptic_f(2,1) is wrong Initial Comment: Maxima says elliptic_f(2,1) is log(tan(%pi/4+1)). That's not right because elliptic_f(%pi/2,1) is infinity. elliptic_f(x,1) also simplifies to log(tan(%pi/4+x/2)), but that's only corrrect if abs(x) <= %pi/2. Not sure what to do about the latter, but for numeric arguments, we should either return infinity or an error.  >Comment By: Raymond Toy (rtoy) Date: 20120819 10:27 Message: Signal an error in this case.
