WebMar 5, 2024 · You need to apply the below given 3 operations on matrix A. Rotation: It is represented as R S where S is an integer in {90, 180, 270, 360, 450, ...} which denotes the number of degrees to rotate. You need to rotate matrix A by angle S in the clockwise direction. The angle of rotation (S) will always be in multiples of 90 degrees. WebMay 30, 2024 · Solution. The inverse of R θ rotates a vector clockwise by θ. To find R − 1 θ, we need only change θ → − θ: R − 1 θ = R − θ = ( cosθ sinθ − sinθ cosθ). This result agrees with (1.4.4) since det Rθ = 1. Notice that R − 1 θ = RT θ. In general, a square n -by- n matrix Q with real entries that satisfies. Q − 1 = QT.
