HW2, Chapter 1 problem 6, Discussion, MA453, Prof. Walther

Problem Statement:

Can somebody please write the problem statement?

A helpful tip to thinking about this question

  • we can describe all rotations by an angle
  • we can not describe reflections by an angle
  • each reflection can be described about the axis it is reflected
  • when two reflections are done in a row, an angle between the axis of each reflection can be found
  • this permutation can now be described by an angle
  • thus it must also be a rotation
