title: Does the .net framework have a build-in method to convert from degrees to radians?
body: <p>I know that I can just say:</p>
  
  <pre><code>radians  = degrees * Math.PI/180
  </code></pre>
  
  <p>However I expect there to be a built in framework method, as it is such a common requirement, however I cannot find one.    Am I not looking hard enough or is it missing from the .net framework.</p>
  
  <p><em>(Please don’t insult me by telling me how to write my own method.)</em></p>
