1. The problem statement, all variables and given/known data Integrate F(x) = x / |x|^3 along the straight line from (1,0,0) to (2,-2,1). 2. Relevant equations Line integral = int (F dot dx) 3. The attempt at a solution I don't know where to start. Usually I do line integrals by parameterizing the line and the vector field but I'm not sure what to do with this. Also, is the field centered at (1,0,0)? I don't really understand the question that well. Is this a conservative vector field? How can I check? Can I use the fundamental theorem of calculus? Is there some sort of potential function I can calculate? I just need someone to bump me in the right direction towards those questions.
