For each complex number $c$, there is an associated quadratic map $f_{c}\colon\mathbb{C}\to\mathbb{C}$ defined by $f_{c}(z)=z^{2}+c$. Since polynomials are analytic, it follows that $f_{c}$ has a Julia set $J(f_{c})$, which we call the quadratic Julia set associated to $c$ and denote by $J_{c}$.

# Show that $\frac{1}{x+2}$ is not uniformly continuous for $(-2,0]$.
I need help proving that $$\frac{1}{x+2}$$ is not uniformly continuous for $$(-2,0]$$, using an $$ε-δ$$ proof.
I understand that intuitively this is just the function $$\frac{1}{x}$$ which is not uniformly continuous on $$(0,1)$$ shifted 2 units to... | {} |

to be fair, I only tested Japanese. こんにちは！
Assuming that texlive is installed. this isnt tested, i reverse engineered this tutorial from my own working install after i got it working.
First, this is the annoying part, you have to install the cyberbit fonts. I have done most of the work for you, gra... | {} |

# Interference of Sound
## Introduction
Sound is described by a pressure wave which can be written as $$\Delta p=\Delta p_0 \cos (kx-\omega t+\phi)$$, where $$\Delta p$$ is the change in pressure at $$x$$ at time $$t$$ from the atmospheric pressure,... | {} |

Hello all
In my calculus book, this problem has been pestering me"
Prove nC(k-1) + nCk = (n+1)Ck, where k > 0 which is read " n choose k-1" + "n choose k"
= n+1C k.
I tried using the formula for the binomial coefficient, but it becomes very messy. I also tried ... | {} |
• ### A further study on Palatini f(R)-theories for polytropic stars(1505.06575)

After briefly reviewing the results about polytropic stars in Palatini f(R)-theories, we first show how these results rely on the assumption of a regular function f(R). In particular, singular models allow to extend th... | {} |

We can first factor the denominator as $$\frac{1}{(x)(x+2)}$$. In order for this to be a terminating decimal, both $$x$$ and $$x+2$$ ... | {} |
