Orthocenter and Translation Parametric Curve Demo

This example demonstrates generating a series of circles through translation operations and exploring their geometric properties related to the orthocenter; core math concepts include orthocenter, translation transformation, parametric curves, exponential functions, and 3D surfaces; construction highlights the use of GeoGebra commands like Circle, Translate, Sequence to create objects c0, pt, t1-t6; suitable for high school and above learners to understand the connection between parametric equations and geometric transformations.
