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)
Finding that integral is pretty difficult. You need to find an approximation with Taylor series, and the answer is not particularly nice...
Isn't there any way to intigrate?
The gamma function is defined as
If it could be integrated then that would be the definition of the gamma function, not the integral.
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.
