title: Evaluate integral from sympy as lambda function
body: <p>I'm using the sympy module of python. I do is this:</p>
  
  <pre><code>x= Symbol('x')
  integrate(x**2+2,x)
  </code></pre>
  
  <p>The answer is:</p>
  
  <pre><code>x**3/3 + 2*x
  </code></pre>
  
  <p>Now, the question is this: Is there a way to make this answer a lambda function of x?</p>
