Hello, I am new to the Mathematica, so please tolerate with my naive question. Here I have a question about the indefinite summation, e.g.
input: Sum[i^3, i] Output: 1/4(-1+i)^2*i^2
If I let i ranges from 1 to 1, e.g. {i,1,1}, the summation is 1. But according to the output expression, the result is 0. Why is that?
Thank you.
