   Explain to me how my code would help you any better than the worked-out   
   formule with its input, partial and full results I already gave.   
      
   Besides, the language I'm using might not be the one you know/are   
   comfortable with, thereby adding yet another layer to the problem.   
      
   First rule of bug-hunting : remove everything that has got zero to do with   
   the problem.

   Alright, here it is :   
      
   lat: -80   Y= -1.059456   
   lat: -50   Y= -0.439171   
   lat: -30   Y= -0.238666   
   lat:    0   Y=  0.000000   
   lat: +30   Y= +0.238666   
   lat: +50   Y= +0.439171   
   lat: +80   Y= +1.059456
