Use - degree measurements converted to radians in order to create the unit circle.

Create/Modify:

Have turtle follow a circular path in order to plot sine, cosine and tangent graphs - model what happens to these graphs when the radius of the wheel is changed, the speed of the wheel is increased or decreased.

Extension:

Using the above program, modify to graph the other three basic trig functions.  

Also create a way to show amplitude, frequency and period.]]> 2017-02-04 17:16:40 UTC https://padlet.com/bstates/SIMMSAlgebra2/wish/151615733 200801310 https://padlet.com/bstates/SIMMSAlgebra2/wish/151616367 possible introduction to the idea of the problem.]]> 2017-02-04 17:28:05 UTC https://padlet.com/bstates/SIMMSAlgebra2/wish/151616367 200801310 https://padlet.com/bstates/SIMMSAlgebra2/wish/151616546 2017-02-04 17:31:30 UTC https://padlet.com/bstates/SIMMSAlgebra2/wish/151616546 https://padlet.com/bstates/SIMMSAlgebra2/wish/151616705 https://www.youtube.com/watch?v=6FByEhgvOb8

Here is a Ferris Wheel Task - from NYC - which could been given to the students to model and solve using NetLogo.

Algebra 2 Standard F-TF5:  Model  periodic phenomena with trigonometric functions.  Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline.
Algebra 2 Standard F-IF4:  Interpret functions that arise in applications in terms of the context.  For a functions that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship.  Key features include:  intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums ; symmetries; end behavior; and periodicity.
Algebra 2 Standard F-IF7e:  Analyze functions using different representations.  ...

*  We think we would like students to be able to have students use the mathematics that they learn to create a model that simulates the ferris wheel situation (and be able to change the parameters of the ferris wheel).
