1. The problem statement, all variables and given/known data Two vectors are given by A = -6 i + 5 j and B = 1 i + 4 j Find A X B (answer only in terms of i, j, k) Find the angle between A and B (answer is terms of degrees) 2. Relevant equations All I was told was that if I set a 3x3 matrix like this: i j k -6 5 0 1 4 0 then AxB is the determinant 3. The attempt at a solution I made the 3x3 matrix and found the determinant to be only -29 k, which I am told is correct. I have absolutely no idea on how to approach the angle problem. If I may ask, can someone get me started in the right direction for that problem?
