 The FAQ entry on homogeneous systems asks the reader to consider the
 following:

 cout << sin(asin(180.0 * degrees));

 There are two problems with this:
 1.  It won't compile because asin does not take an angle.
 2.  Even with the order of asin and sin swapped, the example is confusing
 because it isn't clear if the results should be 180 degrees, or 0 degrees.
 Better to use 90 degrees.
