For each of the following pairs of ordered bases B and ß' for R2, find the change of coordinate matrix that changes B'-coordinates into B- coordinates. (a) B = {e1,e2} and ß' = {(a1, a2), (b1, b2)} b) ß = {(-1,3), (2, –1)} and ß' = {(0, 10), (5,0)} (c) ß = {(2,5), (-1, –3)} and ß' = {e1,e2} d) B = {(-4,3), (2, –1)} and ß' = {(2, 1), (-4, 1)} %3D %3D %3D %3D %3D %3D %3D
