 May 28 awarded Notable Question Dec 22 accepted $\int_\gamma \frac{1}{z\sin z}dz$ where $\gamma$ is the circle $|z| = 5$ Dec 18 comment $|p(z)| \leq M$ for $|z| \leq 1$ Show that $|p(z)| \leq M|z|^n$ for $|z| \geq 1$ Quite nice. Thank you!

That was a terrible mishap. Thank you. Dec 18 asked $\int_\gamma \frac{1}{z\sin z}dz$ where $\gamma$ is the circle $|z| = 5$ Dec 16 comment Proof of $\int_0^\infty \left(\frac{\sin x}{x}\right)^2 \mathrm dx=\frac{\pi}{2}.$ Since $\frac{sinx}{x}$ has a limit of $1$ as $x$ goes to $0$, why can't we just say the residue is $0$?

I would think that all the coordinates need to be changed...
