title: C# Math.Cos(double) returns wrong value
body: <p>In C# I have this:</p>
  
  <pre><code>double Cos = Math.Cos(32.471192290848492); //Equals 0.49299653250335213
  </code></pre>
  
  <p>But when I do this in a calculator I get this </p>
  
  <pre><code>(0.84366148773210745476752872050588)
  </code></pre>
  
  <p>Why is it returning the wrong value?</p>
