This is a remarkable approximation of the sinc function, albeit in a limited range: http://www.wolframalpha.com/input/?i=plo...283%29%2F3 I have no idea why this works, however. Apparently the first four terms are correct. The last term was chosen somewhat arbitrarily to adjust the results to their correct 12 digits. Interestingly the HP-50g, unlike the HP-48, doesn't handle that summation when x = 0. Cheers, Gerson. |
