<h3>Formules Mathématiques</h3>

<p>Voici quelques exemples de formules LaTeX :</p>

<h4>Formules en ligne</h4>
<p>La célèbre équation d'Einstein : \$E = mc^2\$</p>
<p>L'aire d'un cercle : \$A = \pi r^2\$</p>

<h4>Formules en bloc</h4>
<p>Le théorème de Pythagore :</p>
\$\$a^2 + b^2 = c^2\$\$

<p>La formule quadratique :</p>
\$\$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}\$\$

<h4>Matrices</h4>
<p>Une matrice 2x2 :</p>
\$\$\\begin{pmatrix} a & b \\\\ c & d \\end{pmatrix}\$\$

<p>Matrice avec crochets :</p>
\$\$\\begin{bmatrix} 1 & 2 & 3 \\\\ 4 & 5 & 6 \\end{bmatrix}\$\$

<h4>Systèmes d'équations</h4>
<p>Un système linéaire :</p>
\$\$\\begin{cases} x + y = 5 \\\\ 2x - y = 1 \\end{cases}\$\$

<h4>Intégrales et Sommes</h4>
<p>Intégrale définie :</p>
\$\$\int_{a}^{b} f(x) \, dx\$\$

<p>Somme :</p>
\$\$\sum_{i=1}^{n} x_i\$\$

<h4>Graphique de fonction</h4>
<p>Parabole : [graph: f(x)=x^2, x=-5..5, y=-10..10]</p>

<p>Fonction trigonométrique : [graph: f(x)=sin(2*x), x=-3.14..3.14, y=-2..2]</p>

<h4>Lettres grecques</h4>
<p>\$\$\alpha, \beta, \gamma, \delta, \theta, \lambda, \mu, \pi, \sigma, \phi, \omega\$\$
