Hello ^___^
Please help me! Thank you very very much!
Determine if the planes are parallel.
[x,y,z] = [1,2,2] + s[0,1,0] + t[0,0,1]
[x,y,z] = [1,0,3] + s[0,0,1] + t[1,0,0]
thank you ^__^Y

Reiny,
Find a normal to the first plane, and a normal to the second plane.
If the two normals are scalar multiples of each other, then the planes are parallel.
or
try to find their intersection, if you can find a solution, then they are obviously not parallel
