i !How do I find i !,I know it is done by integral found in gamma function,but i cannot integrate it,please help.(additionally,I am a little bad in calculus) #2 20121025 01:35:29
Re: i !Finding that integral is pretty difficult. You need to find an approximation with Taylor series, and the answer is not particularly nice... #4 20121025 15:23:15
Re: i !Hi; If it could be integrated then that would be the definition of the gamma function, not the integral. 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.
