1. The problem statement, all variables and given/known data A = 2i + 3j B = -5i + 6j Calculate (draw vector diagram) A + B A - B 2. Relevant equations actually we're just confused as to whether we need to use the angles to answer this or just answer it directly, meaning that for A + B the answer would be -3i + 9j 3. The attempt at a solution do we use A + B = -3i + 9j or solve for the angles(*rounded off) and use A+B = ((√13)cos56 + (√61)cos50)i + ((√13)sin56 + (√61)sin50)j ????????
