Determine the effect of the following transformations
a) Rotation through pi/2, followed by projection on the Y axis, followed by reflection in the lines y=x.
b) Projection on the X axis followed by reflection in the line y=x.
Determine the effect of the following transformations
a) Rotation through pi/2, followed by projection on the Y axis, followed by reflection in the lines y=x.
b) Projection on the X axis followed by reflection in the line y=x.
It is easy to find the matrix of the rotation and the reflection :
So,
that is, is the reflection in the axis.
Try b) .
