WP QuickLaTeX というプラグインを使ってみた。これもなかなかよさそう。

下記は設定画面で出て来るサンプルの丸コピです。

 

 

At first, we sample $f(x)$ in the $N$ ($N$ is odd) equidistant points around $x^*$:

\[
f_k = f(x_k),\: x_k = x^*+kh,\: k=-\frac{N-1}{2},\dots,\frac{N-1}{2}
\]
where $h$ is some step.
Then we interpolate points $\{(x_k,f_k)\}$ by polynomial
\begin{equation} \label{eq:poly}
P_{N-1}(x)=\sum_{j=0}^{N-1}{a_jx^j}
\end{equation}
Its coefficients $\{a_j\}$ are found as a solution of system of linear equations:
\begin{equation} \label{eq:sys}
\left\{ P_{N-1}(x_k) = f_k\right\},\quad k=-\frac{N-1}{2},\dots,\frac{N-1}{2}
\end{equation}
Here are references to existing equations: (\ref{eq:poly}), (\ref{eq:sys}).
Here is reference to non-existing equation (\ref{eq:unknown}).

こんなのもできるらしい。

\begin{tikzpicture}
[+preamble]
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
[/preamble]
\begin{axis}
\addplot3[surf,domain=0:360,samples=40] {cos(x)*cos(y)};
\end{axis}
\end{tikzpicture}

  • Angel says:

    I much prefer ifnromative articles like this to that high brow literature.

  • Most of the imported gas comes to Slovakia through the pipelines. This is also caused by historical factors. In the years 1945-89, the People’s Republic of Slovakia (bounded politically and economically with the Soviet Union) built the many gas pipelines that linked it with other countries of the soviet bloc, including Eastern Germany (which is important for present energy relations between Slovakia and Germany) to ensure maximal bounds between the USSR and PRP.

  • It sounds like you might be producing difficulties yourself by trying to find to solve this problem instead of searching at why their is often a dilemma in the First place. thanks !!! quite quite helpful post!
