D: m nd a matrix formula for the reection in the mirror 1:: {1.4} + s|[2, 1}. You can leave your answer in the form Mg : FEX P] + P. but you should ll in all the entries of your matrix with numbers. E: Repeat the previous problem with the mirror I? : [3+4] - X = 8. You can leave your answer in the form ME = FEX F} + P, but you should ll in all the entries of your matrix with numbers. Ft Let M: he the same reection as in the previous problem. and let U = [41 3]. For this one prohlmu, it's worth multiplying things out to write your matrix formulas in the form MK + F. [1} Use your work from the previous problem to End a matrix formula for M: o r. [2} Use your work from the previous problem to End a matrix formula for Tu :1 Mr- D ) 1 : ( - 1 , 4 ) + 8 ( 2 1 1 ) me = F ( x - P ) + P Cost = 2 (-1, 4 ) 2 sing = -- Cos 20 = ( 78 /= (15 )= - 4 - 1 5 Sen 20 = 2 ( 2(5 ) ( V8 ) =- 3/5 " me ( ) = F.
