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.


Desmos-enhanced visualizations can coalesce conceptual understanding across Cartesian and polar coordinate systems.
