1. The problem statement, all variables and given/known data Find the matrix that represents a rotation counterclockwise around the origin by 75 degrees followed by a reflection about the x-axis 2. Relevant equations I know that for A rotated counter clockwise you use the 2x2 matirx [cos(theta), -sin(theta)] [sin(theta, cos(theta)] and for a reflection about the x-axis you use the 2x2 matrix [1,0] [0,-1]. 3. The attempt at a solution To be perfectly honest, I am unsure what to do with this information. I don't want the problem solved i just need some guidance, please!
