Graphs of sine, cosine and tangent
Main lesson
The equation from the graph’s features
Use this for “Write a cosine with amplitude 4, period π/2 and midline y = −1.”
Graph of tangent
Use this for “Find the period and asymptotes of y = 2 tan(x/2).”
Model a turning wheel
Use this for “A Ferris wheel is 42 m at the top, 2 m at the bottom and turns once in 8 min. How high is a rider after 2 min?”
