    Parallel Vectors

    Hi,

    The question I am working on is:

    given vectors u = (t, t+1) and v = (3, -4),

    Find all values of t if the given vectors are parallel.

    I have had a go at this but not sure if I have done the right thing.

    I have set (t, t+1) = k(3,-4) since they are parallel.

    This gives me t=3k and t+1 =-4k

    I have then solved simultaneously and got an answer of t=-3/7

    Can anyone give me an idea if I have done the right thing here, I am thinking maybe there is more to this and I have missed something, especially since the question asks for all values of t.

    Thanks

    Re: Parallel Vectors

    Thanks, would there only be one answer for t that could make a parallel vector?

    cheers

    Re: Parallel Vectors

    Well surely the negative of the one given is also parallel...
