WebNov 19, 2024 · These are some good questions. Let me try to answer: Yeah, this is hard. The idea is that we need a function that has poles at the integers and is bounded on a contour as the size of the region bounded by the contour becomes infinite. The function $\pi \cot{(\pi z)}$ fits the bill. But I understand the bemusement at this function just magically … WebThe Wolfram Language can evaluate a huge number of different types of sums and products with ease. Use Sum to set up the classic sum , with the function to sum over as the first argument. Use the Wolfram Language's usual range notation { variable, minimum, maximum } as the second argument: In [1]:=. Out [1]=. This also works for finite sums like :
