(-1)^\infty is an indeterminate expression, like 0/0. Mathematica returns Indeterminate, and maple returns "-1 .. 1" since the limit is bounded, but indeterminate on the interval [-1,1]. Infinity is neither even nor odd. Karl Hegbloom [EMAIL PROTECTED] wrote: > Attached is a session log showing

Attached is a session log showing an error that I receive while attempting to produce a sequence from an expression in Axiom. Maxima seems to have no trouble with the similar expression, and computing the value of the expression by hand, as you can see, seems to work fine also. Another problem I
