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.
(see attached Pdf file)
Can you show me for the first residue with the arrows, or give a hint or a link.

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...
I have a little problem with the integrals of the following functions.
integral from 0to 2pi ∫sin^2(nθ+ψ)dθ=∫cos^2(nθ+ψ)dθ=pi
ψ=the phase angle.They occur in the theory of vibrations.
Is it appropriate to set ψ=0
Below is a fortran program to calculate the roots of an equation by newton's method.
I compile the program with the free compiler g95:
g95 -c newton.f95 then g95 newton.f95 -o newton.exe
When I run the program newton.exe I get the error can't assign value INTENT(IN)::x to...
I use scilab 5.2.2
Ik have a problem to find the zeros or roots of the bessel functions J0,J1...
Whel I write besselj(0,3) I get the value of the bessel function Jo(3)=0,2600520.
Can someone help me how to find the zeros of these bessel functions in scilab.
problrm with complex integral.Consider the integral
use the branch 0<phi<3pi/2 and an idented contour at z=0 and z=1.(circular contour in the

a)show that the integral can be written in terms of the integral...
Use of "Latex"
I want to use Latex.I never heard about latex before.
If it runs on my computer:
1)Where can I download the files I need.
2)How to install
3)Where can I find the source code for writing the mathematical expressions.
I have a problem with the following complex integral.
Integral from 0 to+infinty sin²(a.lnz)/(x - 1)² = pi.a coth(2.pi.a) - 1/2 a>0
I tried different contours and methods,but without result.
Can you help me to find out the complex contour integration.
