Question

Divergence Theorem

Answer 1

I need help with question #2

Answer 2

follow the formula!! there's little twist in the question!

Answer 3

hahah thanks for ur help

Answer 4

is that F(r) = r ??

Answer 5

I need help with questionn #2

Answer 6

but yes that is F(r)=r

Answer 7

\[ \triangledown . f(r) = (i d/dx+ j d/dy + k d/dz).(0i +y j +0k) = 1 \]
\[ \int \triangledown . f(r) dV = 1 * vomue\;of\;cylinder\]

Answer 8

i guess the answer is 2 pi

Answer 9

but like i was reading my book and it makes it sound way more difficult

Answer 10

like u make it sooooo simple. Like what is ur formula that u use?

Answer 11

dot product of two vectors ... :)

Answer 12

which two vectors?

Answer 13

\( \triangledown \) and \( f(r)\) ... I am not sure though ... please check your answer.

Answer 14

is 2 pi answer??

Answer 15

ummm hmmm yes it is
ya it is

Answer 16

looks like I got it ... as long as you have Gauss divergence theorem ... you don't have to worry about surface integrals

Answer 17

well like my book is annoying me with the surfaces and like i dont know how i am suppossed to solve it

Answer 18

surface integrals are terrible ... looks like i should also get some practice

Answer 19

haha thanks :D U really help me out

Answer 20

good revision for me too!!!
