The following adopt the notation [a,b]=(a b)=ai^+bj^. Where I and j are unit vector along the coordinate axes. Calculate each of the following vector sums, expressing your answers in the form used for the question. Feel free to draw diagrams to aid or illustrate your solutions (3i^+4j^)+(5i^-2j^) [3,4]+[2,6] (2i^+6j^)-2(2i^-6j^) [2,6]-[2,-6] (i^+2j^)+(3i^-4j^)-(5i-6j^) [1,2]+[3,-4]-3[5,-6] (1 2)+(4 -3) [a,b]+[c,d] (a b)+(c d) [a,b]-[c,d]+3[e,f] Show transcribed image text
