Example 1: Classic Ferris Wheel The height of a chair on a Ferris wheel in motion can be modeled with a sinusoidal function. The diameter of the wheel is 23m and the passengers board from a platform 0.5m above the ground. The ride lasts 3 minutes and the wheel makes 6 complete revolutions. a) Graph this situation.
The word “sine” comes from the Sanskrit word for “chord”, jīvā. It was mistakenly transformed into the Arab word jiba which means “bosom” or “fold” and then translated into the Latin word “sinus”. The definition of sine in terms of right-angled triangles works only for angles \(\alpha/2\) that are less than \(90^\circ\).
