Homework Help: Integrals of vector functions

  1. Oct 24, 2004 #1
    Can someone check my work and see if I am on the right track please?

    the problem is:

    if r(t) = <e^t, cost, sint> compute integral from pi to 0 of r(t)dt

    so I split it into three integrals, and ended up with (e^(pi) - 1)i + (0)j + (2)k

    does this sound right?

    from pi to 0 or 0 to pi?? If it is from pi to 0 as you said, then all of your answers should have a negative in from of them....unless you meant 0 to pi
