# Asymptotic behavior of nonautonomous monotone and subgradient evolution equations
* Corresponding author
Abstract : In a Hilbert setting $H$, we study the asymptotic behavior of the trajectories of nonautonomous evolution equations $\dot x(t)+A_t(x(t))\ni 0$, where for each $t\geq 0$, $A_t:H\rightrightarrows H$ deno... | {} |

# Why is the Earth Hot?
Not on the surface, I mean, but underneath? As you dig down into the Earth’s crust you will find yourself getting warmer, at a rate of about 0.025°C per metre of depth (25°C per kilometre). But why?
There are two sources of internal heat that make up the Earth’s internal heat budget: radiogeni... | {} |
Problem:
self-dividing number is a number that is divisible by every digit it contains.
For example, 128 is a self-dividing number because 128 % 1 == 0128 % 2 == 0, and 128 % 8 == 0.
Also, a self-dividing number is not allowed to contain the digit zero.
Given a lower and upper number bound, output a list of every p... | {} |

Problem involving partial derivatives.

This is the problem word for word out of my text book:
Given that $$z = \frac{x^3 + y^3}{x - y}$$, x = 10, y = 8, dx = 2, dy = -3, find dz.
Hopefully, someone can tell me where my error(s) are.
This is my method:
$$z = \frac{x^3 + y^3}{x - y}$$

# how to complement the results of cluster analysis with known groups
I have some prior knowledge of grouping, but this may be incorrect or is not sufficient as I need larger number of groups (i.e. subgroups). For example in the following data I have 3 groups in addition to two variables. I would like to use the group... | {} |

# Beautiful proofs(#2): Euler’s Sum
$1 + \frac{1}{2^2} + \frac{1}{3^2} + \frac{1}{4^2} + \hdots = \frac{\pi^2}{6}$
Say what? This one blew my mind when I first encountered it. But it turns out Euler was the one who came up with it and it’s proof is just beautiful!

Rectangular and Polar Coordinates
Any quantity that has two components, can be represented in at least two different ways:
1. Rectangular Coordinates, where the magnitude of the components, can be represented by a point, with respect to a pair of orthogonal coordinate axes.
2. Polar Coordinates, where the two componen... | {} |
# Finding $\limsup_{n\rightarrow\infty} n^{\frac{\log(n)}{n}}$
I was attempting to show that the power series
\begin{equation*} \sum_{n=1}^\infty n^{\log(n)}z^n \end{equation*}
has a radius of convergence of $1$.
In order to do this I decided to use the $\alpha$ method. This meant evaluating the limit
