[QUOTE="kuruman, post: 5003432, member: 192687"] You are on the right track (I didn't check your numbers). Perhaps it is simpler to consider this: once you have vector D = B x C, find a [U]unit[/U] vector in the direction of D. Then take the dot product of this unit vector with A. To find a unit vector in the direction of D, just divide vector D by its magnitude. [/QUOTE]
