We'll test the commands math equations from the article "Minimal Polynomial of 2cos(2pi/n)".

$$ \sum_{k=0}^m (-1)^{\lfloor \frac{k}{2}\rfloor}\binom {m-\lfloor \frac{k+1}{2}\rfloor}{\lfloor \frac{k}{2}\rfloor} x^{m-k} $$

$$ \sum_{k=0}^m (-1)^{\lfloor k/2\rfloor}\binom {m-\lfloor (k+1)/2\rfloor}{\lfloor k/2\rfloor} x^{m-k} $$

We see that the first part wins over the original one (the second one).
