The riddle does not exist. If a question can be put at all, then it can also be answered.

Treating indices as if they were exponents @MattGroff I do not want to find a series. I want to use some umbral-like linear functional to interpret $a^n$ as $a_n$, which is analogous to (35) in this MathWorld article. |

Showing $\int_{0}^{\infty} \frac{\sin{x}}{x} \ dx = \frac{\pi}{2}$ using complex integration @aziiri Recall that $e^{iz} = \cos z + i\sin z$ and use the Squeeze Theorem. |

Umbral calculus with negative indices (and powers) Can you elaborate? |

Umbral calculus with negative indices (and powers) I also think that if $a_{−1}, a_{−2}, a_{-3}, \ldots$ is our infinite sequence, then if we insist on using nonnegative integers we let $\{a_{-n}\}_{n \in \mathbb N} = \{b_{n - 1}\}_{n \in \mathbb N}$. But it seems unconventional and I could not find any articles or books that discuss this. Can you justify it rigorously so that I can give you 50 rep? |
