RE: Summation bug? (HP-49G, 50g)
It seems the term x^(2*k-1) is evaluated by the sum function as x^(2*k)*x^(-1). This can be seen if you enter the summation alone, leave x undefined and press EVAL.
You end up with terms x^M/(C*x). After that, numeric evaluation will attempt to do a division by zero, hence your infinite result. Perhaps if you try a round of symbolic simplification before attempting to do the numeric EVALuation. |
