The following lines (u is a parameter) are known to be on one plane.
L1:r1(t)=<1+2t,-t,2+t>
L2:r2(t)=<ut,3+t,1-2t>
A）Find the value of u.
B）What is the scalar equation of the plane?
2.
Determine whether the vectors u=<1,-1,3>,v=<1,1,2> and w=<2,-4,7> lie in one plane.
-the vectors are in one plane since w(v * u) =0
-the vectors are in one plane since u(v * w) =0
-the vectors are in one plane since v(u * w) =0
-the vectors are in one plane since u(v * w) =1
-none of these
