The matrix representation for a reflection in the line y = mx The matrix representation for a reflection in the line y = mx Let T R 2 →R 2, be the matrix operator for reflection across the line L y = x a Find the standard matrix T by finding T(e1) and T(e2) b Find a nonzero vector x such that T(x) = x c Find a vector in the domain of T for which T(x,y) = (3,5) Homework Equations The Attempt at a Solution a I found T = 0 11 0 b
Reflection across y=x matrix
Reflection across y=x matrix- If $m=0$, then the line $x=0$ is perpendicular to the line $y=0$ at the origin In either case the vector $\begin{bmatrix}m \\ 1 \end{bmatrix}$ is on the perpendicular line Thus, by the reflection across the line $y=mx$, this vector is mapped to $\begin{bmatrix} m \\1 \end{bmatrix}$ That is, we have \A\begin{bmatrix}m \\ 1 \end{bmatrix}=\begin{bmatrix}The handout, Reflection over Any Oblique Line, shows the derivations of the linear transformation rules for lines of reflection y = √ (3)x – 4 and y = 4/5x 4 Line y = √ (3)x – 4 θ = Tan 1 (√ (3)) = 60° and b = 4 The corresponding linear transformation rule is (p, q) → (r, s) = (05p 0866q 3464, 0866p 05q – 2)

Tutorial on transformation matrices in the case of a reflection on the line y=xYOUTUBE CHANNEL at https//wwwyoutubecom/ExamSolutionsEXAMSOLUTIONS WEBSIT3 ⋅ x 1 x 2 x 3 x 4 y 1 y 2 y 3 y 4 When we want to create a reflection image we multiply the vertex matrix of our figure with what is called a reflection matrix The most common reflection matrices are for a reflection in the xaxis 1 0 0 − 1 for a reflection in the yaxis − 1 0 0 1This reflection around y, this is just equivalent to flipping the sign, flipping the sign of the xcoordinate So this statement right here is equivalent to minus 1 times the xcoordinate So let's call that times x1
