This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


This fragment should prove without any doubt that the document used


Here's a sample code.





Si $z_0\in\mathbb{C}$, on a succéssivement
  1 & 0 \\
  0 & 1
  \varepsilon_1\cos\theta \\


enter image description here

  • Well recognized. – Heiko Oberdiek Nov 2 '16 at 23:45
  • thanks a lot, what about the color? the document is not black, it's a little bit gray and smooth? how to apply the same effect for my documents? thanks. – onzepattes Nov 3 '16 at 13:16
  • @onzepattes That's a printer effect. – egreg Nov 3 '16 at 13:17

There are several fonts in the image. An approximation:

\textbf{1.3.}\quad Si $z_0 \in \mathds{C}$, on a successivement
  \overline{\upepsilon_1} \cos\uptheta,
  \exists\uptheta \in [0; 2\uppi[\\
  \mathds{C}, \mathds{U}\\
  \mathcal{H}(f) \cdot \mathcal{L}_{\text{E}}\\
  \Longleftrightarrow \boxed{\left\{ 0 \leqslant \frac{1}{2}\right\}}


The set symbols by \mathds of package dsfont are close, but the result of \mathcal is quite different.

  • No, there's just one font family. Euler and dsfont are out of the question. – egreg Nov 2 '16 at 23:26
