Capareda Curves - Epitrochoids
Loading the math board and drawing, please wait…
This example demonstrates the epitrochoid, a type of Capareda curve, showing its dynamic formation and variations. Key math concepts include parametric equations, coordinate geometry, geometric transformations, and dynamic geometry. The construction uses GeoGebra commands like Sphere, CurveCartesian, and Point, with parameters r, k, q, a controlled via sliders. Suitable for high school and above, it aids in understanding parametric curves and serves as an educational tool for mathematical exploration.
GeoGebra Commands & Parameters
Sphere((0, 0, 0), r) → gCurveCartesian((a * (((q + 1) * cos(t)) - (k * cos(((q + 1) * t))))), (a * (((q + 1) * sin(t)) - (k * sin(((q + 1) * t))))), (b * cos((q * t / 2))), t, 0, ((4 * k) * π)) → dPoint(d) → A
AI Drawing Prompt Reference
