Domingo gets on at point A • Domingo rides the Ferris wheel at the fair. It has a radius of 36 feet. When Domingo gets on the Ferris wheel it is 4 feet above the ground. How far above the ground is Domingo at each point on the Ferris wheel?
Translate cos() into the following • f(x) = - cos() • f(x) = cos(-) • f(x) = cos() • f(x) = cos(/2) • f(x) = 5cos() • f(x) = cos() +10 • f(x) = - cos( - 90)
When the term inside the brackets gets divided by 2 the cosine wave gets stretched by a factor of two. I can generalize that the divisor when inside the brackets will stretch my wave by the factor it divides by.
Graphing sine and cosine • Can you write a function that represents Domingo’s place on the wheel as a function of time? • Use sin or cosine (x) - not both, then translate your equation to fit the graph.
