A majorette in a parade is performing some acrobatic twirlingsof her baton. Assume that the baton is a uniform rod of mass 0.120 kg and length 80.0 cm.

With a skillful move, the majorette changes the rotation ofher baton so that now it is spinning about an axis passing throughits end at the same angular velocity 3.00 rad/s as before. What is the new angularmomentum of the rod?

Prove that $\bigcup _{n\in \mathbb{N}}(-n,\frac{1}{n}]=(-\mathrm{\infty},1]$

I understand that for this to be true, I have to show that $\bigcup _{n\in \mathbb{N}}(-n,\frac{1}{n}]\subset (-\mathrm{\infty},1]$ and $(-\mathrm{\infty},1]\subset \bigcup _{n\in \mathbb{N}}(-n,\frac{1}{n}]$, however, I'm stuck on figuring it out. I think the latter can be proven by contradiction somehow.

Isn't chromatic number just the minimum number of independent sets?

Almost everywhere I read it defines chromatic number as the smallest number of colors needed to color the vertices of G so that no two adjacent vertices share the same color. But if adjacent vertices are of different colours, it seems to mean that adjacent vertices belong to different independent sets. So, I'm almost certain that the definition in title is correct, but I couldn't find a standard source where it is defined like it. So, I'm posting this question to get confirmation.
