title: Continuous Fourier Transform with Python / Sympy (Analytical Solution)
body: <p>I recently replaced Matlab with Python because I was real;y excited by Sympy.</p>
  
  <p>But now I have the following problem:</p>
  
  <p>I need a way to reliably calculate continuous fourier transforms with Python.  Sympy has problems with solutions including Diracs (Delta-functions) as they for example occur for trig-functions etc.</p>
  
  <p>For example, if I try</p>
  
  <pre><code>fourier_transform(cos(x),x,v)
  </code></pre>
  
  <p>the output is <code>0</code> where it should be based on the Dirac delta function</p>
  
  <p>Does anyone know, if this part of Sympy is going to be improved or if there is another way to analytically find fourier transforms with Python?</p>
  
  <p>Thanks for answers or any advice in advance!</p>
