Re: FactorialHi; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #4 20121025 20:43:25
Re: FactorialHi; It is in nested or Horner form for fast computation. The series is best for values >=5 so we put in z = 5.1 We take the exponential of both sides and get. Now to get .1! we use a simple relation: So In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it.

Re: FactorialFor i! use this truncated series: Substituting z = i you get In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #7 20121026 03:25:29
Re: FactorialAlso, for (1+i)!, you can find that using bobbym's answer, since
