Question

CAN SOMEONE PLEASE SOLVE THESE QUESTION ATTACHED TO THIS POST... NEED TO CROSS VERIFY THEM

Answer 1

u gotta be kidding me

Answer 2

a scary face popped in my face o.O

Answer 3

anyway which one do you need help on?

Answer 4

I basically need on 1 and 3

Answer 5

Where are you from, please tell.

Answer 6

Why do you need that info

Answer 7

I have my reasons to ask - basically your nick makes me curious

Answer 8

What do you think @Mikael

Answer 9

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

Answer 10

Lets cut the chase shall we . I hail from India

Answer 11

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

Answer 12

that I know

Answer 13

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

Answer 14

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

Answer 15

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

Answer 16

@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

Answer 17

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

Answer 18

Wait, wait - what is the strange zeta with dot above mean?

Answer 19

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

Answer 20

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

Answer 21

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

Answer 22

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

Answer 23

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

Answer 24

this is simply the z coord.

Answer 25

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

Answer 26

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

Answer 27

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

Answer 28

Now I have solved the question

Answer 29

Aand if u do a Volume integral - it separates in PRODUCT of three identical integrals

Answer 30

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

Answer 31

Thx and post some general outline - in 2-3 simple printed sentences

Answer 32

You seem to be revolve around medal in here

Answer 33

No it is my PERSONAL folly. You know even Newton was a bit after empty honors...

Answer 34

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

Answer 35

So are u a clg student or go to school.
Or work as a teacher or something

Answer 36

or smthng

Answer 37

Ya I will do that in 2-3 days as ringht now I am busy with analog elec
