OK, very good! I wish you luck in your studies.

So, I had a few minutes before bed and figured this would be good to put me to sleep. :smile: I get the same answer as you for the radial integral. However, somehow I got 2 times the answer you did for Er. Of course, I could have made a mistake, but you might want to double check your answer...

Ah, OK! That makes me feel much better. It's unusual to find someone doing field problems with only Calc 1. Yeah, field theory really needs full vector calculus to really sink in well. Well, it will come to you quickly, so no problems. I did this out at work and now don't have the paper with...

Well, above I explained why I thought it was inaccurate and unfair. You can either accept that or not. I feel good that I explained myself. Why it is insulting should be clear. As a scientist/engineer, I don't subscribe to the notion that I can just claim something is true without proof and...

Yes, you did, but ignored my following posts (perhaps inadvertently). That's why I said you need to go back and reread them. Note that anirudh215 nicely asked me for further clarification because you and he are correct that elaboration was needed. I promptly and happily provided further...

Were you insulted? Well, then I'm sorry I insulted you. That was not my intent. I was just expressing my frustration and disappointment. In fact, I was insulted by your comment. You summarized all of my posts with a statement that (EDIT: in fairness, indirectly by agreeing with Dave) "But you...

OK, this is a Calc 3 type problem, maybe you haven't taken this yet, or if you have maybe the concepts are not fully crystalized in your mind yet. The position or coordinate variables are independent, hence the inner integrals can be performed in terms of the inner variables, while treating...

I really get tired of having to explain such obvious things, but very well, if you insist. He said the following: So he is attributing the following things to my statements. 1. I have dismissed the claim before the results are in. 2. I have claimed to have given scientific due diligence. 3...

Look up the inverting amplifier configuation. Then figure out which resistor values will give you each desired output. Then figure out how to use switches to generate the different resistor combinations.

Correct! It almost implies fraud on a higher level than just the man itself. Or, perhaps the man refuses treatment and the doctors have no recourse, but to monitor him. Does anyone know the India laws in this situation?

You need to reread my posts. You are misrepresenting what I said and putting words in my mouth. You are not fooling me, nor anyone else with this tactic.

:smile: Yes, but even plants need water. Anyway, if he keeps this act up, he will need to be planted in the ground very soon.:smile:

I agree that the wording given is confusing, but I wouldn't assign too much meaning to the exact phrasing. No doubt there is a particular meaning intended, and it probably makes sense; but, if it is causing confusion, it's better to just ignore it for now. Basically, GR is the more general...

It's not clear to me why you interpreted Griffith's statement to mean that energy is not stored in the field. It IS stored in the field. Or, at least there is potential energy available when there is a static field. In electrostatics or magnetostatics, the stored energy is not really important...

Try a substitution. Notice that cos(x) is the derivative of sin(x).
