I was given the question,

If u=ai+2j+4k and v=3i+bj+k, calculate a and b
in a textbook from school (revision for a test).

Any thoughts?

I was given the question,

If u=ai+2j+4k and v=3i+bj+k, calculate a and b
in a textbook from school (revision for a test).
It looks like more information is needed to solve the problem. What are the constraints on u and v? Do they need to be parallel, or perpendicular, or something else? If they're just arbitrary vectors, a and b could be anything.
Any thoughts?
Please give us yours first...:wink:
