- Finding the Standard Matrix and the Image In Exercises 11-22, a find the standard matrix A for the linear transformation T, b use A to find the image of the vector v, and c sketch the graph of v and its image. T is the reflection in the y-axis in R2: T(x,y)=(x,y), v=(2,3).arrow_forwardfollowing linear transformation as a matrix relative to the bases {v1, v2} and {w1, w2}. Please give a numerical answer.arrow_forwardDetermine if the statements below are True or False.If it’s True, explain why. If it’s False explain why not, or simply give an exampledemonstrating why it’s false If a 2 × 2 matrix A is non-invertible, then the image of the unit square under thelinear transformation TA is a line segmentarrow_forward
- Assume that T is a linear transformation. Find the standard matrix of T. T: R² R2 first reflects points through the line x₂ = X₁ and then reflects points through the origin. 00 00 (Type an integer or simplified fraction for each matrix element.)

Call it A. b Write the standard matrix of a linear transformation that transforms the second view (with the front view of the green letter C) to the third view (with the front view of the purple letter C). Call it B c Write the standard matrix of a linear transformation that transforms the first view (with the front view of the red letter C) directly to the third view (with the front view of the purple letter C). Call it D. What is the relationship between this matrix and the previous ones? You notice a symmetry in these three views of the solved puzzle. You remember the three pieces of the puzzle were identical in shape. That makes you think that the position of the pieces in the solved puzzle are interchangeable. That is: where the red piece lies…arrow_forwardWhat geometric transformation of 3D space happens in this matrix-vector multiplication? 00 -1 01 0 0 0 ¹)-(3) Please note: All rotation directions to be understood as when looking along the rotation axis towards the origin. The correct answer gets 1 mark. Incorrect answers get O marks.

- Represent vectors using basis More details. Just need (d)arrow_forwardFormat: . If your answer below is a vector, input it as a column vector using the vector/matrix palette tool. • Use * to explicitly indicate multiplication between variables and other variables, between variables and brackets, or between sets of brackets (e.g. x'y rather than xy; 2(x+y) rather than 2(x+y)). Put arguments of functions in brackets (e-g. sin(x) rather than sin x) Give your answers in exact form.
