1. The problem statement, all variables and given/known data You are given a vector field A= kx2 x. a. First, calculate the line integral of A from x=-2 to x=2 along the x axis. b. Next, calculate the line integral of A between the same 2 points, but use a semicircular path with a center at the origin. Recall that in cylindrical coordinates, dl= ds s + sdφ φ + dz z. c. Are the 2 results the same? Explain. 2. Relevant equations 3. The attempt at a solution I believe I did the first part correctly and I got (16/3)k. I am getting confused on the second part though. My value for dl ended up being 2d(phi)phi. This is as far as I could get though.
