2015-10-15 14:11:13 +0100 | commented answer | sage doesn't evaluate Maybe I'm using an older version. The answer I get for f(2).simplify_full() is 3628800 * sum(1/(factorial(k) * factorial(-k + 10)), k,0,2) |

2015-10-14 15:49:11 +0100 | asked a question | sage doesn't evaluate If I say f(x) = sum(k,k,0,x) and then f(2), I get 3, of course, but if I say g(x) = (binomial(10,k),k, 0,x) and then g(2), sage doesn't evaluate, just returns the definition with x replaced by 2. Why? Thanks |
