Creating Parametric Equation Art on the TI-84 Graphing Calculator

"To create parametric equation art on a TI-84 Plus graphing calculator, you must first change the calculator's mode from "Function" to "Parametric." By defining $X$ and $Y$ as functions of a third variable, $T$, you can plot complex, overlapping, and non-linear shapes like hearts, butterflies, and spirographs that are impossible to render using standard $Y=f(X)$ functions. Generating art on a TI-84 Plus—especially the color-screen TI-84 Plus CE—is a sophisticated way to bridge the gap between abstract trigonometry and visual design. As of 2026, the TI-84 series remains the gold standard in secondary and post-secondary mathematics education, an..."
