Understand that most of the quibbling over vectors, component vectors, basis
vectors, projections of vectors, etc. is meaningless to 99% of our students.
They are sufficiently confused over whether the x-component is Asin(theta)
or Acos(theta). It's of course best to be consistent and 'correct', but
getting anal over it won't really help most students. ;-)
