title: how to correctly display the integral on the graph?
body: <p>I counted the integral and I want to display it on the graph, but I wonder how it should be correctly placed on the graph. It seems to me that <code>plt.plot()</code> alone is not enough, or maybe I am wrong, I would like to know the correct way to display this result in a graph.</p>
  <pre><code>import matplotlib.pyplot as plt
  import numpy as np
  from scipy.integrate import quad
  
  
  def integral(x, a, b):
      return a * np.log(x + b) 
  
  
  a = 3
  b = 2
  
  I = quad(integral, 1, 5, args=(a, b))
  print(I)
  
  plt.plot()
  plt.show()
  </code></pre>
