- Every linear transformation x = au + bv, y = cu + dv with ad – bc + 0 maps lines of the uv-plane onto lines of the xy-plane. Find the image (a) of a vertical line u = uo; (b) of a horizontal line v = vo.arrow_forwardLet's say a linear transformation maps a vector m to a vector n, the inverse map of that linear transformation will map the vector n back to vector m. Similarly, the inverse map of an entire composition of linear transformations can be deduced as well. But, it is important to note that the inverse map may not always exist. Consider the following linear transformations in R3: R1: Counterclockwise rotation about the positive x-axis through an angle v R2: Reflection about the x-z plane R3: Orthogonal projection on to the x-y plane R4: Dilation by a positive factor k It turns out that the composition (in any order) of the above transformations has no inverse transformation. Which transformation(s) in the composition may be causing this absence of an inverse transformation?arrow_forwardLet D, be the linear transformation from C'[a, b] into C[a, b] from this example. Determine whether the statement is true or false. Explain. Dfext + 2x) = D,(e**) + 20,64) O False, D, is a linear transformation but does not preserve or produce non-linear transformations. O True, D, is a linear transformation and preserves scalar addition and multiplication. O False, D, is a linear transformation and preserves scalar addition and multiplication. O True, D, is a linear transformation and preserves addition and scalar multiplication.arrow_forward
