Given the vectors
u = (2, 0, 1, -4)
v = (2, 3, 0, 1)
Find any unit vector orthogonal to both of them
I know that two vectors are orthogonal if their dot product is zero...
The Attempt at a Solution
I don't even know how to begin! I know the unit vector for one vector is the vector over its magnitude, but what about two of them? How do I find something that's orthogonal to both at the same time?
Please help ASAP! :) Thanks.
