Project Overview This project is focused on analyzing and interpreting trigonometric graphs. Students model piston motion and vibration behavior using all six trigonometric functions and selected inverse trigonometric functions. Students graph and analyze sine, cosine, tangent, secant, cosecant, and cotangent functions as functions of crank angle, with a strong emphasis on transformations, asymptotes, domain restrictions, and end behavior. Inverse trigonometric graphs (arcsine, arccosine, or arc
