Can anyone explain why evaluating the following expression gives an
error?
Sum[q^(-6 + 4*n)/(1 - q^(-5 + 4*n)), {n, 0, Infinity}] /. {q -> 0.1}
None of the denominators are 0 (would only happen if -5 + 4*n=0, which
is impossible for an integer n, yet I get an error message "Infinite
expression 1/0 encountered" (several times in fact).
Any help on a work around greatly appreciated.
(Please reply to my personal e-mail also).
Thanks,
Jimmy
