Hey, I'm having difficulty with this question.
A Ferris wheel has a radius of 10m and makes one revolution every 12 s. Draw a graph and find an equation to show a person's height above or below the centre of rotation for two counterclockwise revolutions starting at the
highest point of the ferris wheel. ( there were two other points that I have to graph, but if I get this one, I'll hopefully understand the rest)
There was also a picture. It showed a circle ( basically the ferris wheel), and it's divided into 12 "pieces" or parts. Each "piece" is 30 degrees. I was wondering, what would the x and y axis be then? I tried to graph it, and labelled the x-axis as the seconds, and the y-axis as the height in metres. But then...how am I suppose to incorporate the 30 degrees in this??
Have you drawn a picture and labeled things like direction of rotation? It helps a lot in terms of setting things up and lowering a student's confusion level to one manageable enough to deal with using what they already know.
