Let T1 be the reflection about the line 4x-5y=0 and T2 be the reflection about the line -4x-1y=0 in the euclidean plane. (i) The standard matrix of T1*T2 is: [_,_] [_,_] Thus T1T2 is a counterclockwise rotation about the origin by an angle of _____ radians. (ii) The standard matrix of T2*T1 is: [_,_] [_,_] Thus T2T1 is a counterclockwise rotation about the origin by an angle of _____ radians. Solution this is for similar problem Let T1 be the reflection about the line 2x–5y=0 and T2 be the reflection about the line –4x+3y=0 in the euclidean plane. (i) The standard matrix of T1 o T2 is: ? I think these equations are correct... T(v) = A(v) Reflection: A = [((2(u_1))^2)), (2(u_1)(u_2))) (2(u_1)(u_2)), ((2(u_2))^2))] *u being the unit vectors Rotation counterclockwise: A = [cosx -sinx sinx cosx] S o T is the matrix Transformation with matrix AB 3. The attempt at a solution I thought I understood this, but again, I guess I\'ve understood something incorrectly. For the first question, I got the unit vectors to be: [(5/sqrt29)], (2/sqrt29)] and [(3/5), (4/5)] for T_1 and T_2 respectively. I then got the standard matrix A of T_1 to be: [(21/29) (20/29) (20/29) (-21/29)] and the standard matrix B of T_2 to be: [(-7/25) (24/25) (24/25) (7/25)] I then took AB = the dot product of these matrices to get: [(333/6350) (644/6350) (-644/6350) (333/6350)] .
