my first ipython notebook post

my first post with ipynb

from matplotlib import pyplot as plt
import numpy as np
x = np.linspace(0,10,101)

fig, ax = plt.subplots()
for i in range(6):
    y = np.sin((1+i*0.2)*x)
    ax.plot(x, y)

finished tests

this is just some text with some math in it: $x+y = 3 \alpha +\beta$
