Intersection point of 2 vectors in R3
i'm not quite sure where this thread should go but here i go.
I have 2 vectors
Here are the 2 points for vector 1 (in R3)
Here is the symetric equation of vector 2
My parametric equations for those 2 vectors should be :
V1: [LaTeX ERROR:
V2: [LaTeX ERROR:
My problem is that I need to find the unknown a in order for my 2 vector to have one intersection point. I'm missing something but i cannot pinpoint what... and this is driving me nuts. Finding V1 // V2 is easy as well as V1 perpendicular to V2 but i'm missing something obvious.
any help would be appreciated.
