How to add 3 vectors of different directions together?

    For example: 3 Newtons [East30°North] + 5 Newtons [West] + 2 Newtons [West60°South]....

    Thanks!

    I missed the day we went over this in class so it is new to me!

    You need to break up each vector into horizontal and vertical components and then add those together separately.

    So for example if I have a vector that is 5N 75 degree North of East, I would know that
    [tex]F_{x} = 5N cos(75), F_{y} = 5N sin(75)[/tex]
