There are no differential operators in Haskell-98 standard library, nor even polynomial arithmetic. Very probably, there exist application programs treating differential operators. Try to search in http://www.haskell.org If you are going to implement differential operators, try first to implement, for example, polynomial multiplication. After this, differentiation would not look hard. But it depends on what one wants to differentiate, one has to formulate first what kind of expressions are supposed to be differentiated. ----------------- Serge Mechveliani [EMAIL PROTECTED] _______________________________________________ Haskell mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell
