Use your knowledge from 2D transformations to help you find matrices for the following 3D transformations: reflection: - reflection in plane x=0 - reflection in plane y=0 - reflection in plane z=0 rotation: - 90 - 180 - 270 - 45 - Stretch: -parallel to x-axis s.f. 2 -parallel to y-axis s.f. 2 -parallel to z-axis s.f. 2 -parallel to x-axis s.f. k -parallel to y-axis s.f. k -parallel to z-axis s.f. k Enlargment -by scale factor 3 -by scale factor k What would be the determinant of each matrix?
