define s with maple

Try this algorithm

$a=range(3,10);
condition:not(eq($a,0));
$c=range(-7,7);
$b=maple("$a/2*($c)");
condition:not(eq($b,0));
condition:not(eq($b,1));
condition:not(eq($b,$a));
condition:not(eq($b,-$a));
$re = maple("MathML[ExportPresentation]( ($a*(X[n]))+($b*(X[n-1])) =0)");
$s=maple("$b/$a");
$ans=maple("A*($s)^n");

with grading code

evalb($ans=($RESPONSE))

Maybe the key issue is how $s in the above is defined using Maple, and not with the old system that MapleTA is built on top of.

Thanks for the help Alex! You were

Thanks for the help Alex!

You were right about the problem being with $s. I tried your fix, but I got some errors that I couldn't understand. I then tried simply changing the answer to $A*(-($b)/($a))^n and everything worked perfectly from there.

Thanks again :D
