Psi is the balanced polygamma function, which I believe in Maxima is bfpsi. How can I format it so that Maxima can recognize the integral inside the limit?

Several things are wrong here. 2n should be written 2*n. And based on

the image, I think bfpsi(-2,x+1,16) is not what you want. I think the

image says 1/psi(x+1)^2.

In any case, I suspect maxima can't do the limit because maxima can't

figure out what the integral looks like.
