concerning serie representation of psi function.
In te solution of bessel function of the second kind we have the following expressions for the psi functions
psi(m+1) and psi(n+m+1) then they give the series for the two psi functions ie(or digamma function)
k from 1 to m of...
I have a problem with the computation of residues involve the gamma functions.

My question d/ds(s^2 y- s Y(0)-Y'(0).).......
Now Y'= cos(sqrt(t)/2sqrt(t) Y'(0)=infinity
d/ds (Y'(0)=?? can it be treated as a constant or can we change limit and...
