Why is ##V_1## on page 2 defined with respect to ##\pi/2##, shouldn't it be defined with respect to ##\pi##?

Same question for ##V_2## on the same page.

Ah, right.

It's three dimensional spherical coordinates...

here:

And it seems he's stuck at calculating the integral ##\int_0^\infty \frac{\sinh(kz_0)}{\sinh(kL)}kdk##, can you help both of us?

Thanks in advance!

Cheers!

"Getting any single Jackson problem completely correct could be a life’s work!"

LOL!!! wish I had the time to solve completely correctly the 350 problems in the third edition, but I have exams... :-D

$$\frac{1}{4L^2} \left [\psi'\left (\frac{L-z_0}{2L} \right )-\psi' \left(\frac{L+z_0}{2L} \right ) \right ],$$

where

$$\psi(z)=\frac{\Gamma'(z)}{\Gamma(z)}$$

is the socalled "digamma" function.

Does this expression simplifies to the expression in problem 3.19 in Jackson's? i.e with the ##\sec^2##?

$$\frac{1}{4L^2} \left [\psi'\left (\frac{L-z_0}{2L} \right )-\psi' \left(\frac{L+z_0}{2L} \right ) \right ],$$

where

$$\psi(z)=\frac{\Gamma'(z)}{\Gamma(z)}$$

is the socalled "digamma" function.

I assume it's discussed in some group theory for physicists book, but which?

Thanks.

Do I actually need to post it (I mean I assume that you have a legal or illegal copy of the book).

I've found a solution to problem 5.5 from here:

http://pages.uoregon.edu/gbarello/Resources/Papers/Homework/Electrodynamics/HW4.pdf

on page 8 the solution to assignment 5.5b, the last solution has the wrong coefficients, so I wonder where did he go wrong there?

Thanks, jesus and out... :-)

There are some problems about superconducting material which I thought may be found in Tinkham's reference.
