Problem 1: Lucy is riding a Ferris wheel with a radius of 40 feet. The center of the wheel is 55 feet off of the ground, the wheel is turning counterclockwise, and Lucy is halfway up the Ferris wheel, on her way up. Every 90 seconds the wheel does a complete rotation. Write an expression that gives Lucy’s height t seconds after passing her position in problem 1, in terms of t.
Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
