Thread: Line Integral and/or Greens Theorem Problem

I have a homework question that goes like this:

 Evaluate ∫c xz ds where C is the curve with parametric equations:
x= e-t cos(3t) y= e-t sin (3t) z=e-t 0 ≤ t ≤ 2π

I was a little confused with the characters you used, but this is what I got from it:



Where:





Then you can use greens theorem:



Hope this helps.
