just a question though, on the 2nd epsilon identity you used: $\displaystyle \epsilon_{imn}$
what i wanted to ask is: do you have to use the imn notation.. or can you use any preferred notation.. such as ixy....
i understand the final result will still be the same as long as the notation is consistent throughout the solution, but i just wanted to confirm whether imn has to be used as a standard for vector calculus. thanks once again .:o
