- convert a summation to a specific formula
Hello,
Here is my summation:
[itex]sum(1/(25+n*B)),n=0 to (N/2)-1:=A[/itex]
where A is between .01 to 2, N is between 10 to 2000 and I need to find the B for different values of N. I calculate this summation online (check here)
But the Digamma function makes the output function complex and it is not easy to solve with a calculator or even by hand. I need to calculate the result of this summation with hand easily. Is there any way to convert my summation to simple formula? something like this
