an interactive javascripted exercise

For this exercise, study the problem in the box below for a few minutes. Decide how you would translate the words into mathematical language, perhaps writing your thoughts on paper. Then let your mouse wander across the problem, noting how another observer would use and translate the same phrases. And beware: your conscience is watching you!


Prof McFarland felt that the student's main difficulty is the "setting up" process, and he hopes that this web device helps the set up in a new and interesting way. Your comments are eagerly invited!
