the lines l2[/SUB and l3
are given by
l1 : r = 10i + j + 9k + μ(3i+j+4k)
l2: x= (y+9)/2= (z-13)/-3
l3 r= -3i-5j-4k + λ(4i+3j+k)
where mu and lambda are parameters.
d) Show that AC=BC
A(4,-1,1) this was given, I calculated and got B as (5,-1,-2) and C (1,-2,-3)
This I what I did so far
I found AC ( -3,-1,-4)
BC(-4,-1,-1)
I also found the mods of AC and BC to see if they were equal but, they're not.
