May i know the general procedures for evaluating the following line,surface and volume for the following: (1) triple integrate vector A.dV (2) Double integrate vector A.n.dS (3) integrate vector A.dr :bugeye:

Hi, May i know the physical meaning of the following: (1) Curl of a vector field A(x,y,z) (2) divergence of a vector field A(x,y,z) (3) directional deriative of G(x,y,z) (4) gradient of a scalar field G(x,y,z)

Hi, I got a doubt question for this. Given this general expression for the scalar function, G such that del G = F(x,y,z)=2xyi + (x^2 - Z^3)j + (-3yz^2 + 1)k How do i go about finding G?

hi, can someone advise me this question attached. thanks!

hi, can i checked with you..how we normlized Eigenvectors?

hi, can i msn u instead?

or u can try this :http://www.electro-tech-online.com/attachments/math-physics/10356-need-help-eigenvalue-eigenvector-picture-003.jpg?d=1164703364

i re-attached again

does this link wors: https://www.physicsforums.com/attachment.php?attachmentid=8444&d=1164702136

Here's the note :) the one circled, may i know how to get it? Please advise. Thanks!

i will scanned the notes and u hv a look ...cheers :)

Thanks. But the answer for for [a b c] is [1 0 0] any idea how to get [1 0 0]? please advise. Thanks!

Hi Kogs, Do u hv msn? can i msn u to ask something awhile? Thanks!

Thanks! I understand it now. I have another question: [ 2 2 3]a] [ 0 6 6]b] = 0 [ 0 6 6]c] How do i find [a] [b] [c] ? please advise as i pretty poor in matrix.

Can you kindly advise how to get the values of λ1 = 1, λ2=-1 and λ3 =11? As i dun seem to get it.
