Possible Line Derivative Problem?

  1. Nov 10, 2012 #1
    1. The problem statement, all variables and given/known data
    Cacualte the work done by the force field F=(x,y,z) along the path (cos(t),sin(t),t), for 0≤t≤3∏
    2. Relevant equations

    ∫F*ds= ∫F(c(t))dot c'(t) ???

    3. The attempt at a solution
    No attempt, I don't know where to start. I'm not sure how to start it. Notice, I posted question mark by the relevant equation. Do I plug the path equation into the F vector --- take the derivative of the path vector for c'(t)????

    Does this sound right?

    Thanks Simon... I know what to do from there. I just was afraid I was going down the wrong path.
