 fake id(x) for better 2sinh method. tommy1729 Ultimate Fellow Posts: 1,419 Threads: 345 Joined: Feb 2009 05/20/2014, 12:27 PM For improving the 2sinh method so that it works for all bases > eta and other improvements I consider : 2sinh(fake id(x)) fake id(x) behaves like e/2 x for small x, like x for large real and like 0 for large imaginary part. SO what is the best fake id(x) ? Remember we only want a single fixpoint (2sinh(fake id(x))=x) for any base. maybe id(x) = exp(fakelog(x)) ... Thinking... regards tommy1729 « Next Oldest | Next Newest »
