Create a scatter plot for the data you collected or the data above.

Chapter: 6 Problem: 565

Precalculus: Graphical, Numerical, Algebraic 8th Edition
With your calculator/computer in function mode, find values for a, b, c, and d so that the equation \(y=a \sin (b(x-c))+d\) (where y is distance and x is time) fits the distance versus time data plot.

Chapter: 6 Problem: 566

Precalculus: Graphical, Numerical, Algebraic 8th Edition
Make a scatter plot of velocity versus time. Using the same a, b, and c values you found in (2), verify that the equation \(y=a b \cos (b(x-c))\) (where y is velocity and x is time) fits the velocity versus time data plot.

Chapter: 6 Problem: 567

Precalculus: Graphical, Numerical, Algebraic 8th Edition
What do you think a plot of velocity versus distance (with velocity on the vertical axis and distance on the horizontal axis) would look like? Make a rough sketch of your prediction, then create a scatter plot of velocity versus distance. How well did your predicted graph match the actual data plot?

Chapter: 6 Problem: 568

Precalculus: Graphical, Numerical, Algebraic 8th Edition
With your calculator/computer in parametric mode, graph the parametric curve \(x=a \sin (b(t-c))+d, y=a b \cos (b(t-c)), 0 \leq t \leq 2,\), where x represents distance, y represents velocity, and t is the time parameter. How well does this curve match the scatter plot of velocity versus time?
