    Intersection of 2 vectors in 3D, knowing the angle between them

    If we call the point of intersection (a,b,c) and the start point of B (x,y,z), will |B| be sqrt(((a-x)^2,(b-y)^2,(c-z)^2))? With the t's in the values of a,b,c that is going to get messy. Can I call |B| = 1 since I'm really just worried about where a vector going in the DIRECTION of B...

    Intersection of 2 vectors in 3D, knowing the angle between them

    Ok, I get that the point of intersection is going to be some multiple of |A|. And you're saying I can basically call my second vector B [(-.41, .28, -.08)t - (-2.70, -.45, -.21)] since that is the difference of it's two endpoints, which is what a vector is. If I do the dot product of AB then...

    Intersection of 2 vectors in 3D, knowing the angle between them

    ** I accidentally posted this in the pre-calc math section first, but I think it's more applicable here...sorry** Homework Statement I need to find the intersection point of two vectors. For vector A, I have it's start point (0,0,0) and it's magnitude in components (-.41, .28, -.08)...

    Intersection of 2 vectors in 3D knowing the angle between the two

    Homework Statement I need to find the intersection point of two vectors. For vector A, I have it's start point (0,0,0) and it's magnitude in components (-.41, .28, -.08). For vector B, I only know it's start point (-2.70, -.45, -.21) I also know that the angle between the two...
