Web1. @Numth @Calle @whuber: Mathematica make the summation index local using Block. In this way k has a local value for the Sum function. However, k is still k so that g [k-1] translates into Sum [Binomial [k-1,k], {k,0,k-1}] which will evaluate to 0 (because Binomial [k-1,k]=0). What you want is that the summation index gets a different name and ... WebIf If If [ condition, t, f] gives t if condition evaluates to True, and f if it evaluates to False.
