A vector question

<< < (3/3)

unknown id:
would a = -2i-3j-k be an answer as well?

enwiabe:
Yes 'twould. That is the vector going in the opposite direction at 180 degrees to 2i + 3j + k. But it is still a vector perpendicular to both the given ones and has a magnitude of sqrt(14). :)

bucket:
i wish i had chosen spec =[
looks so fun.

enwiabe:
Ah well, you can do it at uni!
