Cosine function decreases as the functional argument increases from 0 to 90 degrees. Hence, cos(6) has greater value.

I assume that 6 and 60 are in degrees and not radians.

1.  Cos Ф = adjacent side / hypotenuse  in a right angle triangle = a/b.
     When angle Ф = 0, a = b and as Ф increases 'a' remains same and b, the    hypotenuse increases. So cos Ф decreases continuously as Ф increases till Ф = 90 deg.

2.  The graph of cos Ф shows the wave like property of Cos and it decreases between Ф = 0 to Ф = 180 deg.

     So  COS 6  is greater than  COS  60.
