I'm very new to Mathematica, so excuse my innocence. I have the following expression:
$$ \left( \sum_{n=0}^r \frac{(-1)^n}{n!} y^n \right)^f $$
I would like Mathematica to expand out the expression in powers of $y$, as a polynomial, where $r$ and $f$ are arbitrary positive integers. Is this possible?
Series[result, {y, Infinity, 0}] // Normal
