Homework Statement
Two vectors are given by the relations
a = 2i-3j-3k
b = 6i+2j+k
Find unit vectors corresponding to a 3- dimensional orthogonal right handed coordinate system where one of the axes is parallel to [itex]_{}a[/itex] and another of the axes is perpendicular to [itex]_{}b[/itex]
Homework Equations
Cross rule: AXB = C
The Attempt at a Solution
I know from cross product that if we have two vectors in a plane then their multiple vector will also be perpendicular to them. So my vector AXB is : 3i-20j+22k ( perpendicular to a and b )
Now I know they want unit vector which is : v/ magnitude of v but in the above case I was told to find the vector : Ax(AXB)...
I am confused about this point. Can anyone clarify for me. Thanks
