Have a look at this Ferris Wheel animation. You can control: radius, middle point, period(time), and you can choose to show or hide lines that indicate the minimum, maximum, and middle heights, as well as a line that follows the height of the rider(orange dot).[br][br]Also have a look at the Curve part. [br]I have already written the curve in the form of: [math]f\left(x\right)=-acos\left(kx\right)+c[/math] . [br]Can you find the curve's correct values for: a, k, c? [br]If you can, the orange dot will track the curve perfectly.[br]Also, do you understand why the [math]cos(x)[/math]function works well for this Ferris Wheel? [br][br]Ask if you're not sure!
