Hi, Bill Page reported this issue, which I'm copying here to the sage-support list, in the hopes somebody will look into it:
sage: var('k, l') sage: f = real(cosh(sqrt(1/2*k-1/2*sqrt(k^2+4l)))) sage: g = f.substitute_expression(imag_part(k)==0,imag_part(l)==0,real_part(k)==k,real_part(l)==l) # the above is all fine. Then: sage: g.full_simplify() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) <ipython-input-4-447f098b1880> in <module>() ----> 1 g.full_simplify() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/symbolic/expression.so in sage.symbolic.expression.Expression.simplify_full (build/cythonized/sage/symb olic/expression.cpp:35488)() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/symbolic/expression.so in sage.symbolic.expression.Expression.simplify_factorial (build/cythonized/sage /symbolic/expression.cpp:37440)() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/symbolic/expression.so in sage.symbolic.expression.Expression._maxima_ (build/cythonized/sage/symbolic/ expression.cpp:5366)() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/structure/sage_object.so in sage.structure.sage_object.SageObject._interface_ (build/cythonized/sage/st ructure/sage_object.c:4781)() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/misc/lazy_import.so in sage.misc.lazy_import.LazyImport.__call__ (build/cythonized/sage/misc/lazy_impor t.c:3000)() /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/interfaces/interface.pyc in __call__(self, x, name) 197 198 if isinstance(x, basestring): --> 199 return cls(self, x, name=name) 200 try: 201 return self._coerce_from_special_method(x) /usr/local/sage/sage-6.3.beta6/local/lib/python2.7/site-packages/sage/interfaces/interface.pyc in __init__(self, parent, value, is_name, name) 624 self._name = parent._create(value, name=name) 625 except (TypeError, RuntimeError, ValueError) as x: --> 626 raise TypeError(x) 627 628 def _latex_(self): TypeError: ECL says: THROW: The catch MACSYMA-QUIT is undefined. sage: -- William Stein Professor of Mathematics University of Washington http://wstein.org wst...@uw.edu -- You received this message because you are subscribed to the Google Groups "sage-support" group.
