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)

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

My calculator has enough memory locations to store each of

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.
