Like the title says i'm not sure when the result is coplanar or collinear 1. The problem statement, all variables and given/known data Are the following vectors in triple product coplanar or collinear? u = i + 5j -2k v= 3i - J w= 5i + 9j - 4k 2. Relevant equations Cross product - place into a 3x3 matrix grid 3. The attempt at a solution After placing them into a 3x3 grid the result is 0. Now i'm not sure if this means they are coplanar or collinear.
