title: Find coordinate by angle
body: <p>I am developing in application in XNA which draws random paths.  Unfortunately, I'm out of touch with graphing, so I'm a bit stuck.  My application needs to do the following:</p>
  
  <ol>
  <li>Pick a random angle from my origin (0,0), which is simple.</li>
  <li>Draw a circle in relation to that origin, 16px away (or any distance I specify), at the angle found above.</li>
  </ol>
  
  <p>(Excuse my horrible photoshoping)</p>
  
  <p><a href="http://www.refuctored.com/coor.png" rel="nofollow noreferrer">alt text http://www.refuctored.com/coor.png</a></p>
  
  <p>The second circle at (16,16) would represent a 45 degree angle 16 pixels away from my origin.</p>
  
  <p>I would like to have a method in which I pass in my distance and angle that returns a point to graph at. i.e.</p>
  
  <pre><code>private Point GetCoordinate(float angle, int distance)
  {
     // Do something.
     return new Point(x,y);
  }
  </code></pre>
  
  <p>I know this is simple, but agian, I'm pretty out of touch with graphing.  Any help?</p>
  
  <p>Thanks,
  George</p>
