Homework Help: Having trouble

  1. Dec 8, 2009 #1
    the problem says:

    find and state the component form of the following vectors.
    c= 3i + 4j P(0,0),Q(5,-2)

    for some reason, i think i ended up doing unneccessary work. I found the Work of the problem instead, which is 7. Is work the same thing as component form? If not, what am I supposed to be looking for?

    Work? How does work enter into a problem that asks for the compenents?

    If v = ai + bj, the horizontal component is a and the vertical component is b.

    If v is the vector from P(a, b) to Q(c, d), v = (c - a)i + (d - b)j and its components are c -a and d - b.
