$\mathcal{Prove}$ ~\mathcal{Prove}~

$\displaystyle \sin(\theta)\ne0,N\in\mathbb{Z}^+\implies\left|\sum_{x=0}^N(\cos(2\theta)+i\sin(2\theta))^x\right|\leq\left|\frac{1}{\sin(\theta)}\right|$

$\displaystyle N\text{ square-free}\implies x^{\phi(N)+1}\equiv x\pmod N$

Square-free and $\phi$ ~\phi~. An example of a consequence is $x^5\equiv x\pmod{10}$ ~x^5\equiv x\pmod{10}~

$\displaystyle x=x_x^x\implies x=x_{x_{x_x^x}^{x_x^x}}^{x_{x_x^x}^{x_x^x}}$

$\displaystyle \sum_{k=0}^N \binom{N}{4k} = \frac{2^N}{4}+\frac{\sqrt{2}^N\times\cos{(45^{\circ}\times N)}}{2}$

In this, find a grid where the ball cannot leave within any finite amount of time, or prove that it is impossible to find such a grid.

In this, prove that the number of perfect solutions is always either 0, or a power of 2.
