title: Plotting two functions simultaneously with matplotlib
body: <p>basically I want to graph two functions</p>
  
  <pre><code>g1 = x*cos(x*pi)
  g2 = 1 - 0.6x^2
  </code></pre>
  
  <p>and then plot the intersection, I already have a module that takes inputs close to the two lines intersections, and then converges to those points (there's four of them) </p>
  
  <p>but I want to graph these two functions and their intersections using matplotlib but have no clue how. I've only graphed basic functions. Any help is greatly appreciated</p>
