- In problem 3a, the order of the transformations at the end of the
problem is revered; "alpha = tau of sigma of rho" should read "alpha
= tau of rho of sigma". The words at the beginning of the problem are
in the correct order. The problem should read:
Show that this isometry is a composition of a reflection, a rotation and a translation, and find the equations for alpha. That is, find sigma

_{m}, rho_{P,theta}and tau_{Q,R}so that alpha equals tau_{Q,R}of**rho**._{P,theta}of sigma_{m} - In problem 3b, "transformation" should read "isometry". So the
problem should read:
Show that

*any***isometry**alpha can be written as a composition of a translation, a rotation, and possibly a reflection.
