Dreamworld is in the process of designing a new ride: The world’s first half underground Ferris Wheel!
They have constructed a scale model to do testing on and are looking to find a way to graph the height of the car above the ground, given the angle it has travelled around the wheel.
Riders board the wheel from the right hand side (As seen from the diagram).
We are looking to investigate the way in which the height of the car changes depending on the angle around the circle.

**θ=angle[C,A,car]**into the input bar at the bottom of the screen and pressing ‘enter’. [list=4]

**S=( θ,y(car))**into the input bar and pressing 'enter' [list=5]

**y= sin(x)**into the input bar and observe the relation with the traced trajectory of 'S' [list=8]
