] | The complex numbers are just a distraction. We can rewrite your example as
$$(-1)^2=1 \implies \big ((-1)^2 \big)^{1/2}=1^{1/2} \implies-1 = \sqrt 1 = 1 \implies -1 =1.$$
Do you see where we made the mistake above? | That's because
$$
(e^{2\pi i})^{1/2}\neq e^{\pi i},
$$
even though their square is equal:
$$
(e^{2\pi i})= (e^{\pi i})^2.
$$
Just like what's in real numbers, every complex number have two square roots. The power $1/2$ placed at the top right corner just gives you one of them. $e^{\pi i}$ is another square root of $1$. |

String[] test = new Str... |
4,170,389 | Recently I came across this summation:
$$\sum\_{k=0}^n\cos\Bigl(k\frac{2\pi}{n}\Bigr)$$ when I was trying to evaluate the following summation $$\sum\_{k=0}^{n} z^k+z^{-k}$$ where $z \in \mathbb{C}, z=\operatorname{cis}(\frac{2\pi}{n})$
But I got stuck... Could anyone give me a tip ?
Thanks in advance! | 2021/06/11 | [

] | $\sum\limits\_{k=0}^n z^k=\frac{1-z^{n+1}}{1-z}$
$\sum\limits\_{k=0}^n z^{-k}=z\frac{1-z^{-(n+1)}}{z-1}$
Is that where you started. | **Hint**:
$\cos\dfrac{2k\pi}n$ is the real part of $\:\Bigl(\mathrm e^{\tfrac{2i\pi}n}\Bigr)^{\!k}$. |
