Envelope Curves Unify Sinusoidal Graphing
Christopher Harrow, Nurfatimah Merchant · Mathematics Teacher Learning and Teaching PK-12 · 2020
Transferring fundamental concepts across contexts is difficult, even when deep similarities exist. This article leverages Desmos-enhanced visualizations to unify conceptual understanding of the behavior of sinusoidal function graphs through envelope curve analogies across Cartesian and polar coordinate systems.
