    If you tell what I asked - the method for all your questions is from the same chapter of knowledge

    OK the whole bunch of them is solved by Green's - Stock's formula/theorem

    Soo compute the Curls and integrate - in many cases the curl completely zero or very simple ==> so very easy to integrate

    All I want to ask and specifically the 3 ques . In this quest the eqn of the function is bot provided only the curl of the function is provided. Now how shall I find the function from its curl

    And conversely: sometimes the line integral [which is fundamentally simpler as it is 1 Dimensional!] will "annihilate" some of the components

    @Mikael the question has already given the curl of the function and now what I have to do is to verify it using general method but the problem is that I dont have the function. And by the way if you curl and curl of a function you will always get 0

  18. punnus

    And Curl is given. Now Find the actual function from the curl is the real task

    It is the unit vector. And it is a unit vecter in the z direction

    CAn't be - because near it IS a unit vector i-with-cap

    The unit vectors ARE clear i,j,k with caps above them

    That has no meaning to with the question it is just the way our prof. writes.

    I have got it - this seems very direct exercise of Gauss-Ostrogradsky theorem http://en.wikipedia.org/wiki/Stokes_theorem

    this is simply the z coord.

    Aand what ques. 3 is asking is to compute the surface integral of Grad(xyz) = yz*i + xz*j + xy*k

    Now read the whole wiki http://en.wikipedia.org/wiki/Stokes_theorem Decide what is more applicable here Stokes or Gauss - Ostrogradsky and get your check

    Yeah one IMPORTANT THING : comlete your surface from ONE octant to full 8 octants and use the symmetry of both the FUNCTIO xyz and the Ellipsoid ===> then u can use Gauss-Ostrogradsky

    You should post the method of solution here - courtesy (and even self interest... for the future). I imagine also that u heard about medals and such

    Aand it would be "morally symmetric" to share the method of solution here for all.
