For each problem...
  1. Figure out where the angle terminates. Since they are multiples of pi%2F2 and pi, you should find that they each terminate on one of the axes.
  2. Since points on the unit circle that are also on an axis have one coordinate that is zero and the other is 1 or -1, all you have to do is figure out which coordinate is zero and whether the other coordinate is 1 or -1. (Drawing a diagram will probably help with this.)
