  1. East (x) = Fx = 4 sin 12 - 3 cos 15
    North (y) = Fy = -4 cos 12 - 3 sin 15

  2. |F| = sqrt (Fx^2+Fy^2)
    tan angle below -x axis= Fy/Fx (assuming both Fx and Fy are negative, Quadrant III)

  5. 15° south of west and 4 N in a direction 12° east of south.
    15° south of west ----> 195° in trig notation
    12° east of south ---> 282° in trig notation

    Resultant = 3(cos 195°, sin195°) + 4(cos282°, sin282°)
    = (-2.898,-.776) + (.832, -3.913)

    = ( -2.066, -4.689) <----- your required answer, same as Damon's answer

    |R| = √((-2.066)^2 + (-4.689)^2 )
    = 5.124

    My calculator has enough memory locations to store each of
    the answers, which I did.

  6. Of course it's not coincidence. You've used the following names on your posts:
    Joe, Eat My Shorts, Yes, Poo, Tati, Crusades , and many more.

    You're lucky you weren't banned for pretending to be a tutor. After this, choose one name, like Joe, and use it on all of your posts.
