We have added code to compare simplified expressions. Closing this bug report as fixed. Dieter Kaiser  Comment By: Dieter Kaiser (crategus) Date: 20100309 00:00 Message: This is an interesting bug which is caused by the comparison with an unsimplified expression. The problem occurs in the routine OFFORMA*F<X>^N+B in solve.lisp. The additional term atan(a/b) or atan(c/b) of this bug report is a constant which should not influence the solvability of the equation. But it does. The first example for atan(a/b) gives the expected answer. The routine OFFORMA*F<X>^N+B returns T. I have put code into the routine to show the values of *HAS*VAR and the result of the call of PDIS: (%i65) solve(tan(x  atan(a/b)) = 0, x); 0: (OFFORMA*F<X>^N+B (#:tan(xatan(a/b))1895 1 1)) OFFORMA*F<X>^N+B : *has*var = (((%TAN) ((MPLUS RATSIMP) $X ((MTIMES RATSIMP) 1 ((%ATAN) ((MTIMES RATSIMP) $A ((MEXPT RATSIMP) $B 1)))))) $X) : pdis.. = ((%TAN) ((MPLUS RATSIMP) $X ((MTIMES RATSIMP) 1 ((%ATAN) ((MTIMES RATSIMP) $A ((MEXPT RATSIMP) $B 1)))))) 0: OFFORMA*F<X>^N+B returned T solve: using arctrig functions to get a solution. Some solutions will be lost. (%o65) [x = atan(a/b)] Now the second example with atan(c/b). For this example the routine OFFORMA*F<X>^N+B returns NIL. The comparison of *HAS*VAR and the return value of PDIS fails. The reason is that *HAS*VAR contains an unsimplified %atan expression with a different order of the arguments. (%i66) solve(tan(x  atan(c/b)) = 0, x); 0: (OFFORMA*F<X>^N+B (#:tan(xatan(c/b))1928 1 1)) OFFORMA*F<X>^N+B : *has*var = (((%TAN) ((MPLUS RATSIMP) $X ((MTIMES RATSIMP) 1 ((%ATAN) ((MTIMES RATSIMP) $C ((MEXPT RATSIMP) $B 1)))))) $X) : pdis.. = ((%TAN) ((MPLUS RATSIMP) $X ((MTIMES RATSIMP) 1 ((%ATAN SIMP) ((MTIMES SIMP) ((MEXPT SIMP RATSIMP) $B 1) $C))))) 0: OFFORMA*F<X>^N+B returned NIL (%o66) [] It is by design of the routines which gives the value of *HAS*VAR (e.g. varsort, newvar, newvar1, fnewvar, ...) that an unsimplified expression with a special order of the arguments is returned. Therefore, it might be the best to improve the test in OFFORMA*F<X>^N+B to be sure not to miss the case of equivalence of two expressions.

File: #P"C:/maxima5.18.1/lisputils/defsystem.lisp" (Form #226) >>>>>>>> I found the solution is to copy a more recent defsystem.lisp library to the lisputils folder. The version supplied with Maxima is:  DEFSYSTEM 3.4 Interim 3. One that works and is bundled with ECL 9 is:  DEFSYSTEM 3.6 Interim. Would it be possible to update to the latest one in the Maxima source repository?  >Comment By: Dieter Kaiser (crategus) Date: 20100703 13:57 Message: This bug report seems to be out of date. Now we have Maxima 5.21. Perhaps we can get a new bug report, when the issue is still present. Setting the status to pending and the resolution to "out of date".
