   Consider the Euler identity:   
      
        iπ   
       e   + 1 = 0   
      
   That only takes that simple form in radians.   
      
   Do you know the Taylor series for e^x? You can use that, and the above   
   formula, to derive Taylor series for sin and cos.   
      
   Also, you have useful properties like   
      
       sin x ≃ x as x → 0   
      
   Again, this only works in radians.
