The orthogonal projection of b onto a is the vector orthab = b - projab. for each of the following parts, draw the four vectors a, b, projab, and orthab on the same set of axes in mathematica. print out and attach the three graphs to your homework. be sure to label each graph and its vectors. you may use the "projection" function in mathematica. пе (a) a = (6,1), b = (1, 2) (b) a = (1,2), b = (6,1) (c) a = (6,1), b = (-2,3) a2) use your graphs from problem a1 to answer the following questions. (a) what is each orthab vector orthogonal to? (b) what is the relationship between b, projab, and orthab? a3) if a and b are both nonzero vectors, under what circumstances is projba = projąb? onzero
