1. The problem statement, all variables and given/known data You are looking down at a map. A vector u with ||u|| = 5 points north and a vector v with ||v|| = 10 points northeast. The cross product u×v points: A) south B) northwest C) up D) down Please enter the letter of the correct answer: The magnitude ||u×v|| = 2. Relevant equations 3. The attempt at a solution it says that the correct answer is "D" why does it point down? it says the correct answer (for the magnitude) is (5*10*sqrt(2) )/2 but i don't even know how to get that. Can someone explain how i'm suppose to get that?
