Hi please show all the steps. Thank you
Calculate the value of the gamma function for n=10.5 & n=11.5. Then
Compare the values to the factorial integral values
for n=10,11 & 12.
Show how to get I(10.5)= 11899423.08396
And 1(11.5)= 136843365.4655 not by numerical integration.
In =
x"e¬* dx
Now using numerical integration we transform it into a sum to get,
I(10.5) 11899423.08396
I(11.5) & 136843365.46556
Now the values for the integers are,
I(10)
= 3628800 ; I(11) = 39916800 ;I(12)
= 479001600
It is seen that,
I(10) < I(10.5) <I(11) < I(11.5) < I(12)
