The skiing community looks to YOU for your expertise. Ski instructors across the globe are interested in how best to teach their pupils. Your company wants to be the leaders in the industry. You must investigate if the “best” path is sinusoidal, parabolic, or circular.

Discussion of Probable Models

Discuss all three models (sinusoidal, parabolic, circular) and rule one out as the least likely model. Be sure to record the major points from your discussion.

ModelingFor the remaining two models, write an equation to model each function through two complete turns (one left and one right). For consistency, everyone should use this window:

Hint: Depending on the models chosen, you may need to write two piecewise functions to complete both turns.

In addition, set your table values to every 0.05 fraction of a curve.
