    [SOLVED] Line Integral.

    Hello
    find the line integral \int_C ydx+zdy+xdz
    where C consist of line segement C1 from A(2,0,0) to B(3,4,5) followed by C2 from B(3,4,5) to C(3,4,0)
    It is not hard I know.
    Lets focus on C1:
    By finding the parametric equations for this line, we will get:
    x=2+t
    y=4t
    z=5t
    Now, finding dx, dz .. etc and substitute them in the integral, easy.
    But the problem how did we know that t is from 0 to 1 ???!
