*My connection screwed up and I ending up posting this thread twice, sorry*
This question in the Vectors exercise of the Edecvel P3 book, seems simple but I end up getting two equations with three unknowns for each one. Its question 7 in Exercise 5D, I've included part (a).
7. Find a vector which is perpendicular to both A and B where:
(a) A= i + 3j - k and B= 2i - j - k
Any help greatly appreciated.
