* #5:  I included some parameters.  Inverse trig functions were not covered in
  6.2; I did not go over them in class; they have not appeared on any chapter 6
  homework or quiz problem.  Therefore, I will not include them on this exam.
  However, I will make it clear to the students that they should know
  antiderivatives involving trig functions for the final.
