We created posters based on this word problem about Don Quixote:

Don Quixote, delusional in his desert quest for adventure, spots a group of windmills in the distance.  Mistaking them for giant monsters he decides to attack one of them.  In an athletic move, he hops off his horse Rocinante and at a height of 3m, grabs hold of an “arm” at the lowest point in its rotation.  The diameter of the windmill is 20m and it completes 1 rotation in exactly 12 seconds on a blustery day. Come up with a trigonometric equation to describe Don’s height (m) relative to time (s) – H(t) – and graph it over one full minute while also answering the following questions in complete sentences.  Hint: draw a picture of the situation trying to fill in as much information as possible before graphing the sinusoidal wave.
