Instructions: On occasion, the notation A = [A, 0] will be a shorthand notation for A = Acos fi + Asin &. Given that A + B = xji+yjj and A - B =xzi+)2j, what is A? O A = 1 (x1 -x2 )i+ 2 ( 1 ->2 )i PA = 1 (x, - x2 )it = ( y1 +>2 )i OA= (x, +x2 )it ? ( y1+y2 )i O A = (x, +x2 )it = (1 1-y2 )i (X1 + X2
