Computing the line integral of the scalar function over the curve

  1. Nov 20, 2011 #1
    1. The problem statement, all variables and given/known data
    f(x,y) = [itex]\sqrt{1+9xy}[/itex], y = [itex]x^{3}[/itex] for 0≤x≤1


    2. Relevant equations



    3. The attempt at a solution
    I don't even know how to start this problem. I thought about c(t) since that's all I have been doing, but there isn't even c(t). I only recognize domain. Can anyone help me please?

    Start with parameterization x = t, y = t3 so your curve is given by
    [tex]\vec R(t) = \langle t, t^3\rangle,\, 0\le t\le 1[/tex]
