    Hi Guys,

    I have an incredibly hard challenge problem... you can find the two pages attached. As you can see, my prof. allows help from anyone/anything... I have no idea to start, but I remember he said that you just need the identities on the 2nd page.

    Any help?

    Thanks in advance.

    Could you repost the pages as images and attach them on your post? It would be very helpful.

    As for your problem: "Cough, Cough... <drama>Physics! NOOOOOOO!!!"

    I hope someone else can help you.

    I hate to be picky, since I 'm not going to help you with this problem, but I think some of the other members mind find these small pictures hard to read.

    It's not letting me delete my other posts either... anyway, third time's a charm.

    Pretty intense proof.

    Do we get the $50 if we solve it? :p

    If I get some help I'd certainly be willing to split it

    I was kidding, actually.

    Though I am interested as to what class/school and what level this question is at.

    Surely there's someone out there willing to brave this problem with me.

    as mentioned, he said it's OK to get help... so in other words, if he was a member, he wouldn't care.

    I'm guessing one of those people who love doing math for the sake of math may be along. Could take a year, but a Good Will Hunting always pops in now and again.

    What level is this course at? undergrad year, etc.

    I'm having trouble calculating the first term -- \nabla^2(E)... could someone at least please help me with that? thanks

    I don't think you will find any help in this forum. Most users' span of knowledge is centered around electronics, not math or physics.

    Maybe you should look elsewhere for help, in a math, or physics forum. If I 'm not mistakes, there are other fora more specialised in these topics.

    Do you understand that the symbol is asking you for the gradient of the vector E? So, the ^2 is grad squared or second order partial deritive of the x,y,z components of the vector E. You will need to understand a good deal of calculus to work this problem. I'm sorry I don't have time to look over it to help more.
