    [tex]\int_C\mathbf{F}\cdot d\mathbf{r}[/tex]


    [tex]\mathbf{r}=\left<1+5t,\,2+2t,\,1+4t\right>;\quad 0\leq t \leq 1[/tex]

    Can you figure it out from here?

    A few hints:
    For the first term, use integration-by-parts, and for the third term, complete the square in the form: [itex]K\sqrt{(t+a)^{2}+b}[/itex], where K,a,b are appropriate constants. Dependent upon the sign of b, we may write [itex]b=\pm{c}^{2}[/itex] where c is some constant.

    See if you manage to make the last few steps on your own..
