Find the Laurent series for $f(z)=(\cosh z-\cos z) / z^{5}$ that involves powers of $z$.
Added by Sandra A.
Step 1
Step 1: Recall the Laurent series expansions for $\cosh z$ and $\cos z$: - $\cosh z = 1 + \frac{z^2}{2!} + \frac{z^4}{4!} + \frac{z^6}{6!} + \cdots$ - $\cos z = 1 - \frac{z^2}{2!} + \frac{z^4}{4!} - \frac{z^6}{6!} + \cdots$ Show more…
