title: Sympy cannot find the laplace transform of sinh (t)
body: <p>I have been using <strong>sympy</strong> for quite a few months now, and recently I have run into a problem. </p>
  
  <p>The following code is supposed to calculate the Laplace Transform of <strong>sinh(t)</strong>. </p>
  
  <pre><code>from sympy import *
  from sympy.abc import *
  laplace_transform(sinh(t), t, s, noconds = True)
  </code></pre>
  
  <p>But, it fails to calculate anything and returns:  <code>LaplaceTransform(sinh(t), t, s)</code></p>
  
  <p>Can anyone tell me what's wrong? </p>
  
  <p>(I am using <code>sympy-0.7.5</code> with <code>Python-2.7.7</code> on Windows 7 SP1 x64)</p>
