Re: Triple vector problem

Ok, I think I got it.

To get the x-component of a vector in standard position, you multiply its length by the cosine of the reference angle; to get the y-component of a vector in standard position, you multiply its length by the sine of the reference angle. Therefore...

x-component of 7 N vector = 7cos(0) = 7

y-component of 7 N vector = 7sin(0) = 0

7 N vector = (7,0)

x-component of 11 N vector = 11cos(105) = -2.847009496

y-component of 11 N vector = 11sin(105) = 10.62518409

11 N vector = (-2.847009496,10.62518409)

x-component of 15 N vector = 15cos(252) = -4.635254916

y-component of 15 N vector = 15sin(252) = -14.26584774

15 N vector = (-4.635254916,-14.26584774)

If this is wrong I'm seriously going to cry.
