$L=\{a^n c b^{2n}\}$$\quad=\{acbb,aacbbbb,aaacbbbbbb,\ldots\}$Here, $\textbf{c}$ acts as center. Push $2$ $a$'s for each $\textbf{a}$ and after $\textbf{c}$ start poppin...

$$P\left(x\right) = \left(\neg \left(x=1\right)\wedge \forall y \left(\exists z\left(x=y*z\right)\right) \Rightarrow \left(y=x\right) \vee \left(y=1\right) \right)$$

The formula used to compute an approximation for the second derivative of a function $f$ at a point $x_0$ is$\dfrac{f(x_0 +h) + f(x_0 – h)}{2}$$\dfrac{f(x_0 +h) - f(x_0 –...
