Kent: Your example is NOT a necessity argument. That is, you CAN introduce
trig with lecture, but there are other ways! Indeed, other ways that MAY be
more effective. For example, providing problem situations that motivate the
desirability of trig and provide a mathematical basis for setting up these
ratios. I have told my trig story recently so will not repeat it here.
I am still waiting for the a solution to: X => lecture.
Historical anecdotes are the closest candidates I've heard so far...
