Ferris Wheel (applications of trigonometric functions)

Phase shift - There is no phase shift for this cosine function so no c value. Vertical shift - Centre of wheel is 18m above the ground which makes the mid line, so d= 18. Lowest point would be 18-15=3m and highest point would be 18+15= 33m above the ground. So the rider will start from 3m ................
