How do I draw force vectors from F1 cos x and F2 cos 2x components?

Homework Statement

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
