given the two lines calculate the angle that is formed by the intersection of the pair of lines
L1:x=-1+3t,y=1+4t,z=-2t
L2:x=-1+2s,y=3s,z=-7+s
i have tried everything even converting these to symmetric equation and figuring out the Cartesian coordiantes for both lines which are for L1(-1,1,0) and for L2(-1,0,7)
then of course taking the dot product and dividing by the magnitude of both and the negative cosine to get the angle
Sorry I made a mistake. They intersect.
I corrected the reply.
BTW: I made the mistake because your equations are hard to read.
Why don’t you bother to learn basic LaTeX??

thanks a lot for your help, perhaps you can have a look at my very similar problem that would be must appreciated
