Question

help....

Answer 1

dont mind that grouchy old guy...ill help you ^_^

Answer 2

when F is a solenoidal vector........
show curl curl curl curl F=dell^4*F...

Answer 3

lol....
i really don't mind:)))))

Answer 4

u guys plzz be serious:(((((((
i've to attend the exam tommorrow in that..........

Answer 5

SIRIUS. -.-

Answer 6

SNAPE. -.-

Answer 7

Okay what is "curl curl curl curl"??? My wrist just cracked from so many curling!
What course is this stuff, on a serious note?

Answer 8

**curling so much

This is vector-stuff, but then? Delta

Answer 9

dell X dell X dell X dell X F.......
plz note that dell is the inverted triangle and something related to vector differentiation...

Answer 10

@lgbasallote u said u'll help.......??????/

Answer 11

nahh i dont know this sorry

Answer 12

it's ok!!!!!

Answer 13

Hmm. vector calculus. I'll have to read this a bit, I guess this is college stuff. Gimme a moment please. (though am guessing we are going to use cross product and then partial differentiation).

Answer 14

dell stands for gradient
\[grad X = (dX/dx,dX/dy,dX/dz)\]
just keep in mind that this are partial derivatives

Answer 15

this curl is (dell X)

Answer 16

butthen this curlF right? which means tendency to rotate?

Answer 17

curl is dell x X
x is vector product

Answer 18

I'm giving up!!!!!!!1
i'll leeave it even if it is given in my exam:))))

Answer 19

it shouldn't be dificult, just make operations

Answer 20

Okay, am sorry @anusha.p I am trying to read up about this, though I don;t think i would be able to understand everything in such a short time. I guess @eliassaab Sir will know about this.

Answer 21

@eliassaab

Answer 22

|x y z |
|X1 X2 X3 |
|dX/dx dX/dy dX/dz|
calculate this determinant by expanding it by elements of 1º raw

Answer 23

raw???????

Answer 24

row

Answer 25

:)

Answer 26

sry, i made mistake, switch places 2º and 3º row

Answer 27

becouse it's dell x X and not X x dell

Answer 28

|x y z |
|dX/dx dX/dy dX/dz|
|X1 X2 X3 |

Answer 29

wat's rhs?

Answer 30

plz u only do the entire problem heeree.....
don't mind........:)

Answer 31

that's lots of operations....................................

Answer 32

you have to calculate vector product 4 times

Answer 33

:)))))
