__F__.

__dr__with

__F__= 3(-y,x,0) from (a,0,0) to (a,0,2πb) along a straight line.

2. Do the same along a circular helix between the two points, parameterised as

__r__= (a cosλ, a sinλ, bλ)

3. Compute the curl of

__F__. How does this relate to the two integral calculations above?

I know Curl = \nabla x

__F__

My notes on this don't seem to be that great, and I'm just completely lost, tbh.

Any help?
