"using residues"...

[Euler]

ok, if you use residue or RESIDUE..make sure that the variable is not used by
the home directory..or something like this..or you will get error messages..

I have two primes and found the error by comparing calculations with the residue function...pretty neat that it works..

Also, the residue function works with both residue(func,z=x) and
residue(func,z,x)...Im pretty sure..the help menu as std is limited..
