1. The problem statement, all variables and given/known data Given, R_1(x) = [ 1 0 0 0 cos(x) -sin(x) 0 sin(x) cos(x)] R_2(x) = [cos(x) 0 -sin(x) 0 1 0 sin(x) 0 cos(x)] R_3(x) = [cos(x) -sin(x) 0 sin(x) cos(x) 0 0 0 1] Describe the transformations defined by each of these matrices on vectors in R3. 2. Relevant equations 3. The attempt at a solution I have no idea how to describe these or even go about figuring it out. Can someone explain to me how to do one of them or at least guide me through the process. Then I can attempt the rest please?
