I once TA'd a Calculus for Business course; there were two fundamental differences between that and the regular course: 1) the problems and exam material were much easier and 2) it lacked any mention of trigonometric functions. When I realized the second part, I went to the instructor and asked: "Without the trig functions, how are they supposed to model and analyze oscillatory phenomena in business settings?". The instructor turned and gave me the biggest smirk I had ever seen.

Ironically they can only do that without the trig functions. Imagine asking somebody on Bloomberg how they would model and quantify the "economic cycle" using trig. :D

    Nah, they slap a few linear variables on it, throw that in a model that adds lag/time dependent variables, and they're ready to tell you the pendulum is starting to swing in the other direction.
