General Formulas for Circle, Ellipse, Hyperbola

This example demonstrates the geometric shapes of circles, ellipses, and hyperbolas along with their general formulas. Key math concepts include quadratic curve equations, parametric representation, and coordinate geometry. Construction highlights involve using GeoGebra commands like Text and If, along with objects such as r, k, h, b, a, c, A, and text labels (text1-text7), to dynamically visualize and annotate curve parameters. Suitable for high school and above students to understand the algebraic forms of conic sections and the relationship between parameter changes and geometric shapes.
