Abstract
In this paper we propose a very specific educational challenge that teachers can use to motivate ambitious and enthusiastic mathematics students who have mastered basic trigonometry and trig functions. The objective is to lead students to a result that will hopefully surprise and entertain and - more importantly - provide a lesson about when and when not to make inferences relating to "numerical error" when using mathematical software and calculators.
