Project for a Trigonometry or PreCalculus class on graphing Trig Functions. Students will bring real-world engineering into your PreCalculus or Trigonometry classroom with this immersive, two-day mini-capstone project! In "The Cummins Acoustic Signature," students step into the role of an NVH (Noise, Vibration, and Harshness) Specialist at Cummins Inc.. Their mission is to design the acoustic profile for a new "Sport" diesel engine targeted at the consumer pickup truck market, troubleshoot harm

Cheat sheet with the Desmos calculator functions needed in AP Statistics. Students now can use Desmos on the AP Exam and this sheet shows simple steps for every function they need, including summary statistics, boxplots, dotplots, histograms, inference procedures, normal curve calculations, linear regression, binomial and geometric distributions. Desmos is much more intuitive for students and once they try it, they'll find it is significantly faster, easier, and has fewer steps than the TI-84.
