title: Uncaught TypeError: Object #<Object> has no method 'Sin'
body: <p>Just puzzling me the Error shown on firebug console:</p>
  
  <pre><code>Uncaught TypeError: Object #&lt;Object&gt; has no method 'Sin'
  Uncaught TypeError: Object #&lt;Object&gt; has no method 'Cos'
  </code></pre>
  
  <p>yet my code gives the value for <strong>Math.PI</strong> </p>
  
  <p>I'm totaly confused, I can't figure out what i did wrong, any help is greatly appreciated.</p>
  
  <p>My code:</p>
  
  <pre><code>function callCordinates(angle){
      console.log(Math.PI); // shows 3.14...
      console.log(Math.Cos(0)); // throws error. :(
  
      var x1 = 480 + 100 * Math.Cos(angle * (Math.PI / 180));
      var y1 = 155 + 100 * Math.Sin(angle * (Math.PI / 180));
  }
  </code></pre>
