How to graph A vecot

  1. Jan 30, 2007 #1
    1. The problem statement, all variables and given/known data
    F1Cosx and F2CosX2 and
    F1Sinx and F2Sinx2

    I need to draw each force vector as an arrow ?
    how do I do that?

    You need to tell us what F1 and F2 are before we can be any help. Without definitions, these are no more vectors than I am a top hat.

    oky, f1=100 x1=20degree
    and f2 200 x2=30 degree

    Well, pick a coordinate system (say the x-y axis). Then the force F1=(100cos20, 100sin20). Since these are just numbers, you can plot the point (100cos20, 100sin20). Join this point to the origin, and you have your force vector. Similarly for F2
