## Homework Statement

You are given a vector field

**A**= kx

^{2}

**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.

## Homework Equations

## 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.
