Hello guys, here's my question is how the book managed to solve this boundary value problem?? can anyone explain it to me in detail?
thanks in advance.
Green's Function for Spherical Problem(Jackson)
- Context: Graduate
- Thread starter Andreol263
- Start date
Click For Summary
Discussion Overview
The discussion revolves around understanding the application of boundary conditions in solving a boundary value problem related to Green's functions in a spherical context, as presented in a textbook. Participants seek clarification on the methodology used in the book and express varying levels of frustration and confusion regarding their own understanding and progress.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- One participant requests detailed explanations on how the book solves the boundary value problem.
- Another participant questions the progress of the original poster, suggesting they may not have engaged deeply enough with the material.
- A participant expresses difficulty in applying boundary conditions and feels there is an underlying issue they do not understand.
- Concerns are raised about the effectiveness of rapidly going through textbooks without solving problems, with one participant suggesting this approach may hinder learning.
- Another participant clarifies that the section in question is not an exercise but rather an explanation of the method, indicating a desire for help with specific equations related to the radial Green's function.
- There is a mention of a previous complaint about another textbook, with mixed feelings about the content and engagement with the material.
- One participant challenges the notion of feeling humiliated and emphasizes the importance of working through derivations to truly learn the material.
Areas of Agreement / Disagreement
Participants express differing views on the effectiveness of the original poster's study methods and the appropriateness of the responses given. There is no consensus on how to best approach the problem or the learning process itself.
Contextual Notes
Some participants highlight the need for a deeper understanding of mathematical concepts and derivations, suggesting that the original poster's approach may lack necessary foundational work. There are unresolved issues regarding the specific application of boundary conditions in the context of Green's functions.

I couldn't apply the boundary conditions normally, there is something more about this problem that i just don't see there, could you help me?

Is this going to be one of those threads where we have to drag it out of you to figure out what you've done?
More generally, this is showing where your plan of getting through a graduate program in physics on your own, in an order of magnitude faster time than physics graduate students breaks down. It's not enough to have seen the prerequisites - you need to know it. On July 24th you were complaining about the first chapter in Boas. On November 12th, you were saying you were nearly done with it. That's very fast, You also said you weren't working through all the problems, and now you are faced with a problem you can't solve because you don't have the math background. Whizzing through a text at lightning speed avoiding the problems isn't going to get you the math.

Well, this isn't a exercise of the book, but a section of the book trying to explain the method, i didn't anything, and my question is HOW he managed to apply these boundary conditions to the radial green function and get these equations below, and other thing, i was complaining about Boas book because the first chapter is REALLY boring, but i managed to understand almost everything in this chapter, the other chapters are VERY fluid and i was having fun with it,and i make a pause in chapter 10 of the book, and another thing, this is a community, where everyone help the others, if you don't want to help just don't post, if you want to indicate a problem in my study plan or even advise a book to reinforce my knowledge, great, i would love this, but come here in a public post and talk like that..., it's ok if you don't want to help, but there's no reason to humiliate me that way.

Humiliate? Then report me to the mentors. Pretending that a strategy that is doomed to fail will succeed does you no favors.
You don't read a textbook like a novel. You need to work out the derivations. If you don't want to do that, you're not going to learn. Having us do the derivations won't help you.
