Let d be the square 0,1] x [0,1] let a -(a1,a2) and b (bi, b2) be nonzero vectors such that neither is a multiple of the other let d be the parallelograrn with vertices (0,0), (a1,a2), (b1mg), and (abi, a b). that is, d is the parallelogram with vertices 0, a, b, and ah. (a) find a linear map t r r taking d onto d. (write the expression for t(, ci) let d be a parallelogram with vertices (0, 0), (1, 3), 2, 0), 3). let d0, x [0, find a linear map 7 such that t(d) d
