Category: Lisp Core - Simplification Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Dieter Kaiser (crategus) Assigned to: Nobody/Anonymous (nobody) Summary: jacobi_cs(x,1) returns a wrong expression Initial Comment: jacobi_cs(x,1) returns a wrong expression: (%i1) jacobi_cs(x,1); (%o1) ''csch(x) (%i2) :lisp $% (($CSCH SIMP) $X) It has to be ((%csch simp) $x). I have observed this problem when trying to exponentialize a simplified jacobi_cs function: (%i3) exponentialize(jacobi_cs(x,1)); (%o3) ''csch(x) But of course it is possible to exponentialize the csch function: (%i4) exponentialize(csch(x)); (%o4) 2/(%e^x-%e^-x) Dieter Kaiser ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=3041267&group_id=4933 |
