Question

A vector field W ( r ) ,

has the value i+3j-2k at the point r=3i-4j+12k.
find Wr, Wtheta, Wfi at that point.

Answer 1

i know how to do this normally, divergence and all other stuff. thou i dont know how to go backwards

Answer 2

a little opinion would be nice instead of giving the whole answer =p
but the questions coming from other people show that the probability of getting a good opinion has lower statistics than doing a hyphersphere integral
