And write some text...

Maybe use some markdown:

Let's embedd a picture:

In [ ]:

!ls

title

LaTeX!

${\alpha \beta \gamma}^2$

In [ ]:

print("hello world!")

In [ ]:

import numpy as np

In [ ]:

x = np.arange(0.,10.,0.1)

In [ ]:

y = 2.0*np.sin(1.5*x)

In [ ]:

%matplotlib inline
import matplotlib.pyplot as plt
plt.plot(x,y)

In [ ]:

from IPython.html.widgets import interact

In [ ]:

def plot_scaled_sin(a,c):
    plt.plot(x,y)
    
    y_interact = c*np.sin(a*x)
    plt.plot(x,y_interact)
    plt.show()

In [ ]:

interact(plot_scaled_sin, a=(0.,3.,0.1), c=(0.5,10.,0.5));
