Sin
Sum

Implemented like:
Extensions - the most significant param is extended and, of course, the first one (usually the enumerator of something)

Changes:
Error does not return a type
Compare returns same value as CompareTo (-1, 0, 1) instead Eq enum (LT, EQ, GT)
FromIntegral just casting int to double
Print and PutStr have additional parameter StringBuilder which return after write

Implementation details:
The mathematical functions like sin, cos, .

are easyilly implemented using System.Math and was not tested
The class use nothing more then System library and Ienumerable interface
The numerict functions are supported only for int and double (Sum, Product)

Not implemented:
pred
succ
undefined
operators - it is not posible define or redefine properly (you have to use standard C# operators)

Use only these functions can be useful for production code or like exercise for work with functions and composition of functions,
but a lot of from prelude has been already implemented in System.Linq.
