\[\begin{equation} E = m c^2 \tag{1.1} \end{equation}\]

2 Examples

2.1 Example 1

Let’s start with a simple Formula:

\[\begin{equation} f\left(k\right) = \binom{n}{k} p^k\left(1-p\right)^{n-k} \tag{2.1} \end{equation}\]

The equation (2.1) is well known.

2.2 Example 2

Another well known formula is the following:

Theorem 2.1 (Pythagorean theorem) For a right triangle, if \(c\) denotes the length of the hypotenuse and \(a\) and \(b\) denote the lengths of the other two sides, we have

\[\begin{equation} a^2 + b^2 = c^2 \tag{2.2} \end{equation}\]

Which is this equation:

3.1.1 Plotting with Python

import seaborn
seaborn.set('paper')
import numpy as np
import matplotlib.pyplot as plt
xx = np.linspace(0, 10, 100)
yy = np.exp(0.1 * -xx) * np.sin(2 * xx)
plt.plot(xx, yy)
plt.grid(True)
plt.show()

4 Testing reference links

First check if you know about theorem 2.1 with the formula (2.2), that famous equation (1.1) and then look up what (2.1) is about!

… and don’t forget the figure 3.1!
