Matrix of a reflection about a line
WebFind the matrix A of the linear transformation T ( x →) = ref L ( x →) ⋅ Give the entries of A in terms of u 1 and u 2. Show that A is of the form [ a b b − a], where a 2 + b 2 = 1. Check back soon! Problem 14 Suppose a line L in R 3 contains the unit vector u → = [ u 1 u 2 u 3] a. WebEquation of Line : y = m x + c slope = m y intercept = c we can relate slope m to angle θ by equation m = tan θ ∴ θ = t a n − 1 m where θ is in inclination of line with respect to x-axis. Translation matrix can be given as T = [ 1 0 0 0 1 0 0 − c 1] Rotation matrix to match the given line with x-axis can be obtained as
